Why Girls With ADHD Are So Often Misdiagnosed

Why most girls with ADHD are misdiagnosed...

For most of my life, I walked around thinking, “Something is wrong with me!”

I would sit in classrooms completely unable to pay attention because my inner world felt far more engaging than whatever was happening around me. My mind was constantly moving. Daydreaming. Analyzing. Creating stories. Thinking about everything except the lesson in front of me.

Except when it came to psychology.

Psychology lit my brain up. I was locked in. Focused. Curious. Hungry to learn more. What I didn’t know then was that this ability to hyperfocus on things I loved was actually part of ADHD.

But like many girls with ADHD, no one noticed.

Instead, I became very good at hiding my struggles.

The ADHD Symptoms No One Saw

I eventually became a therapist working with neurodivergent children, including kids with ADHD and autism. Somehow, these children felt safe with me. They trusted me. And deep down, I think it was because I understood them in a way many people didn’t.

But behind the scenes, I was struggling.

When I wrote notes, words would be missing. I misspelled things I absolutely knew how to spell. My writing looked messy and rushed. Testing had always been incredibly difficult for me. I didn’t figure out how to effectively take exams until my 30s, when I realized I needed to stop trying to answer questions the “normal” way and instead look for patterns visually.

Girls with ADHD are often overlooked because many of us become masters at masking. We compensate. We overwork. We push ourselves harder than everyone else around us.

And from the outside, it can look like we’re doing just fine.

The High-Achieving Girl With ADHD

I passed my licensing exam on the first try in my mid thirties, but by then I had already been diagnosed with ADHD and had started learning what worked for my brain and what didn’t.

For me, learning needed to be visual and repetitive. If I didn’t understand something, I would research it endlessly until I understood it inside, outside, and sideways.

When I first learned Cognitive Behavioral Therapy (CBT), I remember sitting there thinking, “What does this even mean?”

Now? I could probably write a thesis on it! I understand it deeply enough that I help my clients change thought patterns, build confidence, and challenge beliefs they’ve carried for years.

That’s the thing about ADHD girls and women. We often work twice as hard just to keep up, but because we are capable and intelligent, people miss the struggle underneath.

ADHD in Girls Often Looks Like Anxiety

Many girls with ADHD are misdiagnosed with anxiety first because anxiety is what people see on the surface.

They see:

• Perfectionism

• Overthinking

• Emotional overwhelm

• Panic

• Low self-esteem

• Trouble starting tasks

• Difficulty keeping up with school demands

• Social struggles

• Burnout

What they often don’t see is the ADHD underneath it all.

I hid my ADHD incredibly well, but internally I constantly felt like an imposter. I believed I had only gotten as far as I did because I was "lucky," not because I had worked harder than almost everyone around me.

I was diagnosed at 33 years old by a psychologist who was also my friend. I still remember her hugging me with tears in her eyes after giving me the report.

She told me that many people with ADHD burn out long before getting this far in their careers. But, honestly? I was pretty darn close!

Suddenly, My Entire Life Made Sense

Once I finally accepted my diagnosis, everything clicked.

The late nights finishing projects at the last second with my mother, who also has ADHD.

The procrastination.

The overwhelm.

The feeling that no matter how much I achieved, I still wasn’t “enough.”

I know what it feels like to carry that shame quietly.

And I think that’s exactly why I connect so deeply with the children, teens, and young adults I work with now.

Because the stories they tell me are stories I know well.

The overachiever.

The perfectionist.

The girl who looks like she has it together on the outside while internally she’s exhausted and overwhelmed.

Supporting Girls With ADHD and Anxiety

The overwhelm is real, not just for girls, but for parents too.

Parents often ask:

• When should I push?

• When should I step back?

• How much support is too much?

• How do I help without creating more anxiety?

There is no one-size-fits-all answer because every child with ADHD is different.

That’s why treatment needs to be individualized, supportive, practical, and compassionate.

At The Social Mind Counseling, I work with tween, teen, and young adult girls with ADHD and anxiety using evidence-based approaches including CBT and Exposure Response Prevention (ERP). My goal is not to “fix” girls with ADHD, because they are not broken.

My goal is to help them understand how their brains work, build confidence, develop tools that actually help, and recognize that they are capable of incredible things.

Because, they are!

And if your daughter is struggling and quietly wondering if she’s enough, I want her to know something I wish I knew much earlier:

There was never anything wrong with her in the first place!
