How to Stop Overthinking

& Break Free From the Exhausting Mental Loop

Overthinking is exhausting.

You replay a conversation you had three days ago and somehow manage to find twelve new things you could have done wrong.

You get a slightly different text from someone and immediately start wondering whether they are annoyed with you.

You have a decision to make, so naturally you think about every possible outcome until you are somehow less sure what to do than when you started.

And then there are the nights where your body is begging for sleep while your brain decides 11:47pm is the perfect time to investigate every questionable decision you have made since 2014.

If you have been like this for years, it is easy to assume:

This is just my personality.

I am an overthinker.

My brain just works this way.

I used to think exactly the same thing.

I know what it feels like to analyse everything, second-guess yourself constantly and feel as though your brain never completely switches off. But one of the biggest things I learned was that overthinking is not simply a personality trait.

Your nervous system plays a huge role in it.

Why Your Nervous System Can Keep You Stuck in Overthinking

When you have been overthinking for years, it can feel like your brain is simply wired that way.

But often, your mind has learned that thinking things through again and again helps you feel more prepared, more in control and less likely to be caught off guard.

Your brain tries to predict what might happen, work out what somebody meant, prepare for every possible outcome and stop you from being caught off guard.

The problem is that eventually the protection becomes exhausting.

Maybe the overthinking started because you were trying to understand something, make a decision or work out what might happen next.

But after a while, you are not finding new answers anymore.

You are just mentally exhausted, desperate to relax and wishing your brain would be quiet for five minutes, while your thoughts keep spinning anyway.

The good news is that your nervous system is not set in stone.

The patterns it learned can change. You can use practical techniques and daily regulation to help calm your nervous system and make feeling safe, settled and grounded more familiar to your body.

Over time, your system can become less likely to expect something to go wrong, which means your mind does not need to work quite so hard to protect you, and the overthinking naturally starts to ease.

Find Out Why Your Nervous System Keeps Getting Stuck

If you have spent years wondering why you overthink everything while other people seem able to just... have a thought and then get on with their day, take my free Nervous System Archetype Quiz.

In my quiz, these protective patterns are grouped into four nervous system archetypes, each with its own way of overthinking, reacting to stress and trying to feel safe.

Discovering yours can help you finally understand why your mind works the way it does, what tends to trigger your spirals and what your nervous system actually needs to calm down.

Understanding your personal pattern is the first step towards changing it.

What Is Overthinking Actually Doing?

Not all thinking is overthinking.

Sometimes you genuinely have a problem that needs solving.

You need to decide whether to take the job. You need to work out how to approach an awkward conversation. Something has happened and you need to decide what to do next.

Useful thinking usually moves you somewhere.

You gather information, consider your options and eventually reach an action, decision or conclusion.

Overthinking is different.

You keep returning to the same question without getting any new information.

Did she sound annoyed?

What if I made the wrong choice?

What if this happens?

Why did I say that?

What if they think I am weird?

You think harder because your brain believes that somewhere inside the next ten minutes of analysing is the answer that will finally make you feel safe.

But often there is no new answer available.

What overthinking is actually doing is trying to create certainty and safety.

Your mind keeps going back over the same information because it believes that if it thinks hard enough, it might finally spot the danger, prevent the mistake, avoid the rejection or find the “right” answer.

The problem is that a lot of the things we overthink do not have a definite answer yet, so your brain keeps searching anyway.

And that is why the loop continues.

Why Do I Overthink Everything?

There is rarely one single reason.

For some people, overthinking is mostly about fear of making the wrong decision.

For others, it is fear of rejection, uncertainty, criticism, losing control or not knowing what somebody else is thinking.

Often, several of these get tangled together. Here are a few examples:

You Are Trying to Prepare for Something Going Wrong

If your nervous system is already on high alert, uncertainty can feel much more threatening than it objectively is.

You receive:

“Can we talk later?”

Your rational mind has four words.

Your nervous system has somehow produced an entire Netflix drama.

What happened? What did I do? Is it bad? Have I upset them? Are they leaving? Am I in trouble?

Thinking through every possibility can feel useful because your brain is trying to make sure nothing catches you by surprise.

But imagining twenty frightening possibilities does not actually give you more information.

It simply gives your body twenty things to react to.

You Are Trying to Prevent Rejection

Overthinking often becomes particularly intense around other people.

You replay conversations because you want to know whether you said something wrong.

You analyse somebody's tone because you want to know whether they are upset.

If this is one of your biggest triggers, you may also want to understand why you panic when someone is upset with you and why it can be so difficult to let the feeling go.

You rewrite messages five times because you want to make absolutely sure you cannot be misunderstood.

If rejection, criticism or somebody being unhappy with you feels threatening to your nervous system, your brain can become incredibly focused on preventing it.

That is one reason overthinking and people-pleasing often show up together.

You Are Trying to Make the Perfect Decision

Sometimes overthinking is an attempt to guarantee that you will never regret anything.

You compare every option, imagine every outcome and keep searching for the choice that comes with absolutely no risk.

Unfortunately, that choice usually does not exist.

So instead of helping you decide, your mind gets stuck trying to achieve a level of certainty that real life cannot give you.

Your Nervous System May Have Learned This Pattern Early

This does not mean everyone who overthinks had a terrible childhood.

Sometimes there is one obvious experience behind the pattern. Sometimes there are lots of smaller ones.

• Maybe mistakes were heavily criticised.

• Maybe someone's moods were unpredictable and you learned to pay close attention to tiny changes.

• Maybe keeping people happy helped you avoid conflict.

• Maybe you were bullied, excluded, embarrassed or repeatedly made to feel that getting something wrong had consequences.

• Or perhaps you cannot point to anything specific at all.

Over time, early experiences like these can shape how strongly your mind and body respond to stress and possible threat.

Thinking ahead then becomes a form of protection:

If I can predict it, maybe I can stop it.

If I analyse everything, maybe I will not get hurt.

If I understand exactly what happened, maybe I can make sure it never happens again.

That strategy may once have helped you feel more prepared.

It just does not know when to switch off.

A lot of this happens subconsciously. You are not usually sitting there deliberately thinking, If I analyse this enough, I can keep myself safe.

Your nervous system can react to something it reads as a threat before your conscious mind has even caught up, and then your brain starts doing what it has learned to do: analyse, predict, replay and prepare.

All you really notice is that you cannot stop thinking and you are absolutely exhausted by it.

How to Stop Overthinking When You Are Already Spiralling

When you are already deep in an overthinking spiral, trying to force yourself to stop thinking or “think positive” is a bit like trying to prevent a car crash when the car is already doing 100mph towards a brick wall 50 feet away.

Fighting with your thoughts usually will not slow the whole system down. This is why you need to move your attention to the body first.

If your nervous system has learned to go on high alert over things like a short text, a comment from a co-worker or an awkward moment, it can react as though there is a real threat and then struggle to come back down by itself.

That is where regulation comes in. Certain techniques and activities can help down-regulate your nervous system, which basically means giving your body signals that there is no immediate danger.

Once your system starts to recognise safety, it can begin switching off the warning alarms that are keeping you tense, alert and mentally on guard.

Think of it like trying to have a calm, rational conversation while a fire alarm is blaring in the background.

You can try, but everything still feels urgent. Calming your body helps turn the volume of that alarm down, which gives your mind a much better chance of slowing down too.

The goal is not to magically make every thought disappear. It is to get your body calm enough that you can look at the situation without your nervous system making every possibility feel like an emergency.

You’ll discover which of the four protective patterns you lean towards most and what your particular nervous system needs to feel calmer and safer.

Ground Yourself in What Is Actually Happening

Put both feet firmly on the floor.

Look around and deliberately notice the signs that you are safe right now.

Feel the solid ground underneath your feet or the chair supporting your weight.

Notice the door, your bed, the walls around you, your pet nearby, anything that reminds your body that you are here, in the present, and nothing is attacking you.

Then use your senses:

5 things you can see: Really look at them. What colour are they? What shape? What texture?

4 things you can touch: Feel your clothes, the chair, a blanket, the floor. Notice whether they are soft, smooth, warm, cold or rough.

3 things you can hear: Maybe a clock ticking, a faint sound outside or your pet breathing.

2 things you can smell: Your perfume, washing powder, coffee, the room around you.

1 thing you can taste: Even if it is simply the taste already in your mouth or a sip of water.

Then take a few slow breaths, allowing your exhale to be relaxed and slightly longer.

This works because overthinking pulls your attention into imagined problems, future possibilities and things you cannot control.

Grounding deliberately brings your attention back to real sensory information in the present moment, helping your nervous system notice: I am here, and I am safe right now.

You are helping your body recognise the difference between thinking about danger and actually being in danger.

And when your body's alarm starts to soften, your thoughts often lose some of their urgency too.

That creates a positive feedback loop: your body becomes calmer, so your thoughts feel less threatening, which helps your body become calmer again.

Get the Overthinking Out of Your Head and Onto Paper

This is one of the most useful things you can do because trying to answer an overthinking brain entirely inside the same overthinking brain can get... messy.

Keep a few pages in your journal specifically for spirals.

When you notice yourself looping, write down:

Step 1: Brain-Dump the Entire Spiral

First, get everything out of your head.

Write down every thought that keeps looping, even if it sounds dramatic, contradictory or irrational. Write the fears, the feelings, the possible explanations, the imaginary conversations and all the what ifs.

If your friend has sent you an unusually short text, that might look like:

She sounded off with me.

Maybe I annoyed her.

Was it something I said yesterday?

Maybe she is getting fed up with me.

What if I have done something wrong and she just isn't telling me?

Do not edit it or try to be rational yet. Just empty your brain onto the page.

This alone can help because your mind no longer has to keep mentally holding and rehearsing every thought.

You have put it somewhere physical where you can actually see it, rather than trying to keep track of twelve possibilities at once inside your head.

Step 2: Ask “What Is This Story Saying About Me and About Them?”

Now look underneath the spiral.

If your fear is My friend sent a short message because she is annoyed with me, what would have to be true for that whole story to be accurate?

What is your mind saying about them?

Maybe:

She secretly gets annoyed with me but does not tell me.

She judges small things I say.

She would suddenly become distant instead of just talking to me.

And what is your mind saying about you?

Maybe:

I must be really easy to get annoyed with.

One wrong comment is enough to make someone pull away from me.

I have probably done something bad without even realising it.

Seeing it written this plainly can be surprisingly powerful, because you can suddenly see how far the overthinking has travelled from she sent a short text.

You may know perfectly well that your friend is not secretly judging your every word, and you probably do not genuinely believe that one imperfect interaction makes you unbearable either.

It helps you recognise the worst-case story your nervous system has built around the situation, rather than automatically experiencing that story as fact.

Step 3: Come Up With More Balanced Possibilities

Now ask yourself:

What else could be true?

If your friend sent a short text, your mind may have immediately decided she is annoyed with me. But that is only one possible explanation.

• Maybe she was in a rush and did not want to leave you on read.

• Maybe she is tired today.

• Maybe she is busy, distracted or stressed about something completely unrelated to you.

• Maybe she did not even realise her message sounded different.

• Maybe she is simply having an off day.

The point is not to convince yourself that one of these explanations is definitely true either. It is to remind your brain that the frightening explanation it jumped to is not the only possibility.

When you are overthinking, your mind can narrow in on the worst-case interpretation and treat it as though it is the most likely one.

Deliberately coming up with a few calmer, realistic alternatives helps widen that view again, so the situation starts to feel less threatening and your nervous system has less reason to keep sounding the alarm.

Move the Stress Through Your Body

Sometimes you can physically feel overthinking.

Your shoulders are tight. Your chest feels restless. Your jaw is clenched. You feel like you need to do something, even though there is nothing useful to do.

Movement can be really helpful here.

• Go outside for a walk and let your body move while your attention takes in what is around you.

• Put music on and dance around your kitchen.

• Stretch.

• Bounce gently.

• Shake out your arms and legs.

Somatic shaking can simply mean allowing your body to shake, wiggle, bounce and move rather than forcing yourself to sit completely still while you feel intensely activated.

You are giving some of that restless activation somewhere to go while also changing your sensory environment.

And if dancing around your kitchen looking mildly unhinged makes you laugh at yourself, honestly, bonus points.

Try EFT Tapping When Your Thoughts Feel Emotionally Charged

EFT tapping can be another way of slowing everything down when an overthinking loop feels particularly emotional.

You gently tap through a series of points on the face and upper body while acknowledging what you are feeling.

For example:

Even though I am scared they are annoyed with me, I am safe right now.

Or:

Even though I desperately want to know what is going to happen, I can allow myself not to have the answer yet.

You do not have to pretend the fear is ridiculous or force yourself to believe something you do not believe.

The combination of rhythm, physical sensation, slower breathing and naming the emotion can help bring you out of the purely mental loop and back into your body.

Research on EFT has also found measurable reductions in physiological stress markers such as cortisol, showing that its calming effects are not necessarily just happening in your head.

How to Stop Overthinking When Nothing Bad Has Even Happened

Sometimes overthinking does not start because of a text, a conversation or something going wrong.

Sometimes you finally sit down to relax and your brain suddenly decides to replay an embarrassing moment from six years ago, remind you of everything you need to do tomorrow, invent a completely hypothetical future problem and then revisit three old conversations for good measure.

And if your brain seems to save all of this specifically for bedtime, I have a full guide on how to stop overthinking at night.

When there is no obvious trigger, the same basic approach discussed in the above section still applies.

The difference is that body-based regulation becomes even more important, because there may not be one specific situation to journal about or “solve.”

Use grounding. Go for a walk. Shake out some of the tension in your body. Try EFT tapping. Take a few slow, deep breaths with a longer exhale.

The aim is to help bring your nervous system out of that restless, alert state so your mind has less fuel to keep jumping from thought to thought.

And do not only use these techniques when you are already spiraling.

Practicing them regularly, even on relatively calm days, helps your nervous system become more familiar with settling back down.

Over time, that can make it easier to return to a calmer baseline, so those random overthinking spirals may start happening less often and feel less intense when they do.

How to Become Less of an Overthinker Long Term

Daily nervous system regulation matters because it has a cumulative effect. The more often you practise grounding, movement, slow breathing or other calming techniques, the more familiar your body becomes with coming back down from stress.

Over time, that can help stop some overthinking spirals before they even properly begin.

But if you want to change the pattern long term, it is also worth understanding what tends to trigger your overthinking and why those things feel so significant to you.

If you are extremely sensitive to rejection, criticism, somebody's mood changing or the possibility that you have disappointed someone, there is usually a reason those situations create such a strong reaction. This is where journaling can become really useful.

If criticism is a particularly big trigger for you, you might also recognise that horrible feeling that everyone is judging you, even when you do not actually know what anybody is thinking.

Try this powerful journaling practice

Imagine a co-worker makes a negative comment about something you have done and you spend the rest of the day replaying it.

Instead of filling your journal with thoughts about them, bring the attention back to yourself.

What actually happened?
My co-worker criticised part of my work.

What did that make me feel?
Angry. Embarrassed. Defensive. Not good enough.

Then keep gently following it:

Why did feeling “not good enough” bother me so much?

What did their comment seem to say about me?

Does this feeling remind me of anything else?

Maybe you eventually realise that criticism has always hit you particularly hard because growing up, mistakes were often pointed out and you desperately wanted approval.

You were trying your best, but criticism made you feel as though your best was never quite enough.

Suddenly, the reaction at work makes a little more sense. It was not only about one comment. The situation touched an older sensitivity your nervous system already knows very well.

That understanding gives you something much more useful to work with than simply telling yourself to “stop overthinking.”

And always try to finish your journaling by building yourself back up.

You might write:

What evidence do I have that I am actually good at my job?

I work hard. I show up. I care about doing things properly. I am willing to learn. I have handled difficult things before.

Then remind yourself of qualities that have nothing to do with your performance at all:

I am kind. I am caring. I am thoughtful. I am understanding. I am loyal.

You do not need to do deep journaling every day. Even doing this a couple of times a month around different triggers can help you understand the patterns underneath your overthinking.

The more you recognise where those reactions come from, challenge the old story and practise responding differently, the less power those same triggers may have the next time they appear.

You Are Not Stuck Being an Overthinker Forever

If you have been overthinking for years, it can start to feel like this is simply who you are.

But overthinking is not your identity. It is a pattern your mind and nervous system have learned to rely on, and learned patterns can change.

You can learn to catch the spiral earlier.

You can calm your body before your thoughts run away with you.

You can understand the triggers that send your nervous system into high alert, work through the deeper reasons they affect you so strongly and slowly make safety feel more familiar than constant anticipation.

And over time, something starts to shift.

The short text does not ruin your whole evening.

The awkward conversation does not need to be replayed seventeen times.

The embarrassing memory pops into your head and, instead of launching a full investigation, you think ugh, that was awkward... and carry on with your day.

That is the goal. Not to never have an anxious thought again, but to stop every thought from turning into a three-hour mental loop.

And if you want to understand your own overthinking pattern more deeply, take my free Nervous System Archetype Quiz.

The quiz groups these patterns into four archetypes and discovering yours can help you understand what sends your nervous system into overdrive, why your mind reacts the way it does and where to start helping it feel calmer and safer.
