Why You Overthink Everything — And Can't Switch Off

By Keeley Matthews, Relational Psychodynamic Counsellor - 6 minute read

Relational psychodynamic counselling for high-achieving women in Epping, Essex, with in-person sessions in Loughton and online across the UK.

You know that feeling when you just want your head to be quiet?

Not calm, not peaceful — just quiet. When you're so exhausted by your own thoughts that you'd do almost anything to make them stop.

Maybe it's 11pm and you're still going over something that happened at 2 in the afternoon. Maybe your body is tired but your mind won't follow. Maybe you've noticed a tension you carry — in your shoulders, your jaw, your chest — that's been there so long it just feels like you now.

I know how that feels. The self-hatred. The panic. The exhaustion of it.

And I want to tell you something that I genuinely believe: you are not your thoughts. Right now, you are not seeing yourself clearly.

Your mind isn't broken. It's busy on purpose.

Overthinking isn't random. It's your mind keeping itself occupied — subconsciously, deliberately — so that something underneath doesn't get a chance to come up.

Because feelings are uncomfortable. And your mind has learned, somewhere along the way, that busy is safer than still.

So it replays. It analyses. It scans for what you might have missed, what you might have got wrong, how you might have come across. It keeps you one step ahead — or tries to — because one step ahead feels like control. And control feels like safety.

What's really underneath it

In my experience — and I include myself in this — the women who overthink the most are the ones who are always on alert.

Frightened, on some level, of being seen. Of being judged. Of getting it wrong. Of what other people think of them, whether what they said landed correctly, whether they've been misunderstood.

And underneath all of that, something quieter:

If I can anticipate what someone needs, I will be safe. I will be loved.

So they think ahead. They read the room. They manage, they anticipate, they try to get there first — because if they can just stay one step ahead, nothing will go wrong. Nothing will be taken away.

I used to do this too. I would anticipate people's thoughts, their actions, their needs — and find myself genuinely confused, hurt and resentful when it didn't bring back the warmth or the relief I thought it would. Sometimes I'd cause problems that weren't even there to begin with. The very thing I was doing to feel safe was the thing making me less safe.

That's the cruel irony of it.

What it feels like to live there

It's not just exhausting. It's physical.

It's a shortness of breath. A feeling like you can't quite get enough air in.

It's nervous energy running under your skin that you can't shake off, no matter what you do.

It's tension held so tightly, for so long, that your body stops registering it as tension. It just becomes you.

I carried pain in my left shoulder blade for years. Physio helped, temporarily. It wasn't until I was well into my own therapy that I noticed one day — it had gone. I hadn't even seen it leave.

That's what chronic alertness does. It lives in the body. And it stays there until something shifts underneath.

Why it gets louder when you slow down

This is the part that catches people off guard.

You finally stop. The day is done. There's nothing left to do. And instead of relief — your mind accelerates.

That's not failure. That's what happens when the structure of the day drops away and there's nothing left to keep the feelings at bay. Your mind has been busy for a reason. When it can't be busy anymore, what's been sitting underneath has more room.

So it fills the silence the only way it knows how. With more thinking.

And then the shame arrives

And if the overthinking itself wasn't enough — there's often a second wave.

When you're exhausted by your own thoughts, when you've been going round in circles for what feels like hours, the inner critic shows up.

Why can't I just stop this? Everyone else seems to manage. Why is this so hard for me?

That comparison is one of the cruellest parts of it. Looking around at other people who seem fine — who seem to just get on with things, who don't appear to be quietly unravelling on the inside — and concluding that the problem must be you.

It brings up a deep shame. A feeling of not being good enough. A sense that you should be able to control this, and the fact that you can't is just more evidence of your own failing.

But here's what I want you to hear: the women who sit across from me are some of the most capable, self-aware, hardworking people I know. And almost every single one of them has said some version of that same thing. Why can't I just stop?

You are not the only one. You are not failing. And the fact that you can't think your way out of this isn't weakness — it's actually the whole point. Because this was never just about thinking.

You are not the version of yourself you hear in your head

For many women, this way of being becomes so familiar it stops feeling like something they do and starts feeling like who they are.

The one who thinks things through. Who anticipates. Who gets it right.

But that voice — the one that tells you you've said the wrong thing, come across badly, missed something important — that voice isn't the truth of you. It's protection. It's old. It learned to sound like you a long time ago.

The real you is underneath all of that. She wants to be recognised. She wants to be set free.

And I say that not as something I've read, but as something I know. Because I've been there. And therapy changed it for me — not by silencing the thoughts, but by helping me understand where they came from. The more I understood, the less I needed them.

That's what I want for you too.

I work with women in Epping, Loughton and Buckhurst Hill, and online across the UK — and this is one of the things I hear most in my consulting room. Not always in those words, but in some version of them. The exhaustion. The not being able to stop. If that's what brought you here, you're in the right place.

If any of this has landed — the exhaustion, the tension you didn't realise you were holding, the sense that your head just won't go quiet — I'd gently invite you to find out more about working together on the Work With Me page.

Or if you recognise that feeling of never quite being enough despite doing everything right, you might want to read Why You Feel Like an Imposter — Even When You're Not or The Hidden Cost of Being the 'Capable One first.

If the exhaustion underneath all of this feels familiar, you might also want to read The Exhaustion Nobody Sees.

Either way — I'm glad you found your way here.

If any of this resonates, you're welcome to find out more about how I work — or to book a free 15-minute consultation. It's just a conversation, with no pressure to commit to anything.

I offer both in-person sessions in Loughton and online-therapy across the UK.

If this feels familiar, you're not alone in it.

The RelationSHIFT Counsellor

Keeley Matthews is a relational psychodynamic counsellor holding a Post Graduate Diploma in Psychodynamic Counselling and is a member of the BACP. She works with high-achieving women in Loughton and online across the UK — and has lived experience of the patterns she writes about. She knows what it is to build defences that work, and what it takes to understand what they cost you.

In brief: Overthinking isn't a habit you can simply decide to stop — it's the mind staying deliberately busy so that uncomfortable feelings don't get a chance to surface. For many high-achieving women it developed early, as a way of staying one step ahead and in control when things felt uncertain or unsafe. Understanding what's underneath the noise, rather than trying to silence it, is usually what allows it to quieten.
