Could my anxiety and overthinking have been ADHD all along?
I Was the Quiet, Anxious Child No One Worried About
The Hidden Side of ADHD in Girls (And What I See Now as a Counsellor)
This blog explores what it’s like to be the “quiet one” who never caused concern, yet felt anxious, different, and constantly on edge inside. It explores how this can be linked to ADHD that often goes unnoticed in girls, and how those early experiences can follow you into adult life, showing up in overthinking, self-doubt, and emotional fatigue, and how counselling can help you make sense of it and feel more like yourself again.
ADHD is often imagined as the child who can’t sit still, the one disrupting the class, the one teachers can’t ignore.
But I couldn’t have been further from that.
I was the quiet one, the good one, the anxious one. The child who appeared to sit calmly and do what was expected, while inside my mind felt anything but calm. My thoughts moved quickly, jumping from one thing to another, trying to keep up with everything at once.
And because I wasn’t causing problems for anyone else, no one really saw how much I was struggling.
Why have I always felt anxious, even when nothing was wrong?
Some of my earliest memories are of anxiety.
Not the kind that comes and goes, but something that felt constant. A steady undercurrent in my body, as though something wasn’t quite right, even when everything around me looked fine.
When we were out, I would cling tightly to my mum’s leg. Not in a playful way, but in a way that felt urgent, as though letting go would mean facing something I didn’t feel equipped to manage.
Everything could feel like too much. The noise, the movement, the unpredictability. Even small situations could feel big internally. Walking into a room, not knowing where to stand, worrying about getting something wrong before I had even begun.
I didn’t have the language for this. I just knew I felt different.
How did no one notice I was struggling when I seemed fine?
At school, I wasn’t the child teachers needed to manage.
I was quiet, polite, and well-behaved. The kind of child who follows instructions and keeps their head down.
From the outside, that can look like coping. It can even look like thriving.
But what I understand now, both through my own experience and through my work as a counsellor, is that quiet doesn’t always mean okay.
Often, it reflects a child who is thinking constantly, monitoring themselves, trying hard to get things right, and holding far more internally than anyone realises.
Being the “good one” comes with pressure. You learn early that being easy and agreeable keeps things smooth.
But it also means there is very little space for you.
Learning to Be Who I Needed to Be
School is where I became very skilled at adapting.
Without realising it, I learned how to be different versions of myself depending on who I was with. One for teachers, one for friends, one for keeping everything manageable.
I became highly attuned to other people. I could sense shifts in mood, read a room quickly, and adjust myself in ways that helped things feel stable.
At the time, this felt like a strength.
But it came at a cost.
Because when you are constantly adjusting to others, you lose connection with yourself.
Now I understand this as masking.
At the time, it simply felt necessary.
The Exhaustion No One Could See
Each day after school, I would come home and feel completely drained.
This was not just tiredness, but a deeper kind of exhaustion that sat in my body. I often wondered why I needed so much time to recover when others seemed to carry on.
Looking back, it makes sense.
My mind had been active all day. Filtering, monitoring, adjusting, overthinking.
Masking is not just something you do outwardly. It is something your whole system carries.
Over time, that level of effort becomes exhausting. And when you are the quiet one, that exhaustion often goes unseen.
What I Understand Now (That I Didn’t Then)
Looking back now, both personally and through my training as a counsellor, I can see something I didn’t have the words for at the time.
This was not simply anxiety.
It was a nervous system under strain, alongside a mind processing more than it could comfortably hold. It was also the beginning of patterns that made sense in the moment, but continued into adulthood.
Patterns like overthinking, people-pleasing, feeling responsible for others, and believing you need to get things right to feel okay.
These are patterns I now see in many of the women I work with.
How This Shows Up in Adult Life
These patterns grow with you.
From the outside, you may still appear to be coping well. You may be seen as capable, reliable, someone who has things together.
But internally, it can feel very different.
Your mind may rarely feel quiet. Thoughts loop, conversations replay, and there is a constant sense of trying to work things out.
You might find yourself questioning what you said, how you came across, whether you got something wrong.
In relationships, this can feel even more intense. Small shifts in tone or behaviour can feel significant, and you may find yourself trying to interpret what they mean.
There can be a strong pull to keep things steady. To avoid conflict, to smooth things over, to make sure everything stays okay.
Over time, this creates a deep sense of fatigue.
Many women describe feeling tired in a way that is hard to explain. Not just physically, but mentally and emotionally. Tired from thinking, from holding things together, from rarely feeling able to switch off.
There can also be confusion, especially when life looks fine on paper.
Why does this feel so hard?
How do I stop overthinking and feeling like this all the time?
When I first came into counselling, I didn’t have the language for any of this.
I just knew that things felt harder than they seemed to for other people. My mind felt busy, my emotions felt intense, and I spent so much energy trying to keep everything steady.
Counselling gave me space.
Not to fix myself, but to understand myself.
At first, it was simply having somewhere to say things out loud that I had carried for years. Thoughts that had looped quietly in my mind suddenly had somewhere to go.
And slowly, things began to make sense.
Beginning to Understand, Not Judge
One of the biggest shifts was moving away from self-criticism and towards understanding.
Instead of asking what is wrong with me, I began to ask what has happened that makes this make sense.
That softened everything.
The overthinking, the people-pleasing, the constant scanning. These were not flaws. They were ways my system had learned to cope.
Seeing My Patterns Clearly
Through counselling, I began to notice my patterns more clearly.
How quickly my mind moved to worst-case scenarios.
How easily I overrode my own needs.
How much energy I used trying to get things right.
These were not things I needed to remove.
They were things I needed to understand.
The Shift That Changed Everything
The biggest change was not that everything became easy.
It was that I no longer felt completely pulled around by my thoughts.
There was space.
Space to pause.
Space to notice.
Space to choose differently.
And this is something I now see in the clients I work with.
How This Shapes the Way I Work Now
Because I have lived this and worked through it myself, I do not approach counselling from a distance.
I understand how real this feels.
In my work, we explore what is happening underneath the surface. We look at patterns like overthinking, people-pleasing, emotional intensity, and the pressure to get things right.
And we understand them in context.
Not as flaws, but as responses that made sense.
What Clients Often Begin to Experience
Over time, things begin to shift.
Clients often notice they do not spiral in the same way. They feel less responsible for everything and everyone, and begin to trust themselves more.
Relationships can feel more steady, less driven by fear and over-analysis.
There is often a growing sense of not having to hold everything together in quite the same way.
It Is Not About Becoming Someone New
This work is not about becoming a different person.
It is about coming back to yourself.
The version of you that is not constantly adapting or trying to get everything right.
A Small Shift That Changes Everything
One of the most meaningful changes is the ability to pause.
A moment before automatically responding or adjusting.
And within that pause, there is choice.
Final Thoughts
For a long time, I believed that being the good, quiet one meant I was coping.
Now I understand that sometimes the people who appear the most okay are carrying the most internally.
Ready to Understand Yourself in a Different Way?
If you’re recognising yourself in this, counselling can offer you a space to explore what is happening underneath the surface in a way that feels safe and manageable.
As a counsellor in Thurrock, and working with clients online across the UK, I support women who feel capable on the outside, but who feel this constant inner pressure.
You do not have to continue managing this alone.

You were never “too much”.
You just learned to hold a lot… very quietly.
