Understanding Your Mind: A Path to Peace
Overthinking can feel exhausting.
Your brain never switches off.
You replay conversations, analyse text messages, panic you’ve upset someone, and struggle to relax even when nothing is technically wrong.
There was a time when I genuinely believed overthinking was simply part of my personality.
I thought I was:
- too sensitive
- too emotional
- too intense
- too much
My brain never switched off.
I replayed conversations before bed, analysed text messages, worried I’d upset people, rehearsed situations before they even happened, and constantly felt like I was trying to get life “right.”
What I understand now, both personally and professionally, is that overthinking is often not a personality flaw at all.
It’s a nervous system that doesn’t feel safe.
And for many people with ADHD, anxiety, trauma, eating disorders, or people-pleasing tendencies, overthinking becomes a form of self-protection.

What Is Overthinking, And Why Does Your Brain Do It?
Your brain is designed to protect you.
Years ago, our nervous systems helped us survive physical danger. If something threatened us, our body flooded with adrenaline and cortisol so we could run, fight, or protect ourselves.
The problem is that modern danger is often emotional rather than physical.
Now the “threat” can become:
- rejection
- embarrassment
- conflict
- judgement
- failure
- not fitting in
- disappointing people
Your body reacts as if danger is present anyway.
That’s why overthinking can feel exhausting physically, not just mentally.
When Anxiety Shows Up in the Body
Overthinking Symptoms: When Anxiety Shows Up in the Body
Overthinking is not just “thinking too much.”
It can feel physical.
For me personally, it shows up as:
- cold fingers
- dry mouth
- adrenaline
- nervous wheezing
- restlessness
- feeling wired but exhausted
- zoning out
- my brain is buzzing at 100 miles an hour
- wanting to overtalk
- or sometimes completely freezing and struggling to get words out properly
There have been moments where my brain is moving so fast internally that my mouth almost feels paralysed.
That’s not stupidity.
That’s nervous system overwhelm.
When the body is overloaded, executive functioning often drops offline.
Nervous System Anxiety and Fight or Flight
Is Overthinking a Sign of Mental Illness?
Not always.
Overthinking can sometimes be linked to:
- anxiety
- ADHD
- trauma
- depression
- chronic stress
- burnout
- eating disorders
- perfectionism
- nervous system dysregulation
For many people, overthinking develops as a coping strategy.
Your brain starts scanning constantly for danger, rejection, mistakes, or emotional discomfort because somewhere along the line, it learned that being hyper-aware felt safer than relaxing.

ADHD, Rejection Sensitivity, and the Fear of Being “Too Much”
One of the biggest things that made this click for me personally was understanding my ADHD.
Growing up, I constantly felt different.
I spent years trying to:
- mask
- fit in
- avoid rejection
- get things right
- not upset people
- seem “normal”
That creates hypervigilance.
You start monitoring everything:
- Did I say the wrong thing?
- Was that awkward?
- Are they annoyed at me?
- Do they like me?
- Am I too much?
- Have I explained myself properly?
For many people with ADHD, rejection feels incredibly intense emotionally.
So the brain adapts by becoming over-responsible, hyper-aware, people-pleasing, and perfectionistic.
The exhausting part is that most people around you have absolutely no idea how much mental energy goes into all of this.
Emotional Overwhelm and ADHD
The Presentation I’ll Never Forget
I remember having to stand up and deliver training in front of colleagues while working at Young Healthy Minds.
These were people I trusted.
People who genuinely supported me.
But my nervous system didn’t care about logic.
I stood there sweating, completely overwhelmed, trying to present from a PowerPoint, and my dyslexia completely kicked in.
I couldn’t read the words.
My brain froze.
I started stuttering.
Eventually, I just admitted it:
“I can’t read the words. My brain’s not working.”
And honestly?
That vulnerability changed everything.
Instead of judging me, people helped.
They stepped in.
They supported me through the presentation.
That moment taught me something important:
Shame grows in hiding.
Sometimes, nervous systems calm when we stop pretending we’re okay.
Why Overthinking Happens in Relationships
Overthinking often becomes strongest in relationships because relationships involve emotional safety.
If somebody fears rejection, abandonment, criticism, or conflict, the brain can start trying to predict problems before they happen.
This can show up as replaying conversations over and over in your head, analysing text messages for hidden meaning, constantly seeking reassurance, over-explaining yourself, people pleasing, trying not to upset others, or assuming you’ve done something wrong even when you haven’t.
The brain believes it’s helping protect you.
But over time, living in a constant state of emotional scanning becomes exhausting.

When Overthinking Starts Making Your World Smaller
Overthinking eventually changes behaviour.
You avoid things.
Cancel plans.
Stop trusting yourself.
Withdraw socially.
Delete the post before anyone sees it.
Talk yourself out of opportunities.
I’ve had moments where I became so overwhelmed travelling that I convinced myself I was on the wrong train, got off, panicked, got on another train, then convinced myself I was wrong again.
I’ve posted content online, deleted it because I thought it sounded ridiculous, then reposted it later and received lovely feedback.
That’s what overthinking does.
It constantly tries to prevent discomfort before anything has even happened.
Exploring the Impact of Overthinking
Is Overthinking a Sign of Depression or Chronic Stress?
Sometimes overthinking can be linked to depression, burnout, or chronic stress.
When the nervous system stays activated for long periods, the brain becomes exhausted.
People can begin feeling:
- emotionally drained
- mentally stuck
- disconnected
- hopeless
- numb
- irritable
- unable to switch off
This is why nervous system regulation matters so much.
Not because people are weak.
But because the body cannot stay in survival mode forever without consequences.
Sometimes You Need Food Before You Need Mindfulness
This is something I think gets massively overlooked online.
When people are anxious and dysregulated, they often stop checking in with their body altogether.
They forget to eat.
Blood sugar drops.
Cortisol rises.
Everything suddenly feels catastrophic.
Now, when I notice:
- cold fingers
- dry mouth
- zoning out
- adrenaline rising
I know my body needs regulating before my thoughts will calm.
And honestly?
Sometimes the answer is incredibly simple.
If I’m too anxious to eat properly, I’ll drink half a Huel shake, leave it 20 minutes, then come back to it once my nervous system settles.
That small amount of nourishment helps my brain come back online again.
Not every solution has to be profound.
How to Stop Negative Overthinking Without Shaming Yourself
Honestly, if somebody tells me to:
meditate
journal perfectly
name five things in the room
that’s probably not the first thing my brain reaches for when I’m overwhelmed.
And I know many ADHD or highly anxious people feel exactly the same.
Sometimes regulation needs to be realistic.
For me, that looks like:
noticing physical signs early
eating something simple
stepping away briefly
reducing overwhelm
slowing things down
asking for support
being honest instead of masking
The goal is not becoming perfectly calm all the time.
The goal is understanding your nervous system with more compassion.
Sometimes You Need Regulation Before Mindfulness
We Were Never Taught How to Fail Safely
I think one of the reasons so many people overthink is because we were taught mistakes meant something about our worth.
At school, we learned:
- get it right
- succeed
- perform well
- don’t fail
- don’t embarrass yourself
But nobody really taught us:
- how to regulate discomfort
- how to recover from mistakes
- how to be imperfect
- how to fail without shame
One of my values in therapy is asking:
“What was the golden treasure in the failure?”
Because growth rarely comes through perfection.
It usually comes through honesty, reflection, and learning.
If Your Brain Feels Exhausting, You Are Not Broken
If you recognise yourself in this, I really want you to understand something:
Overthinking often makes sense.
Especially if you’ve spent years:
- masking
- walking on eggshells
- trying to fit in
- fearing rejection
- trying to stay accepted
- trying to get everything “right”
Your nervous system may simply be trying to protect you.
And honestly?
Most people are far too absorbed in their own lives to analyse you as deeply as you analyse yourself.
I know that sounds blunt.
But sometimes that truth is freeing.
