ADHD Misdiagnosis in Women: Not Anxious, Actually ADHD

ADHD in women is often missed or misdiagnosed as anxiety, depression, or ‘not trying hard enough.

“Just Anxious, Just Moody, Just Lazy”: The Cost of ADHD Misdiagnosis in Women and Girls

For a lot of women, an ADHD diagnosis doesn’t arrive in childhood. It arrives in their 20s, 30s, 40s, or even later—after years of being told they’re:

• Too emotional

• Too disorganised

• Too sensitive

• Not trying hard enough

By the time someone finally says, “Hey, this might actually be ADHD,” the damage is often already done.

This isn’t just an identity issue. ADHD misdiagnosis in women (or no diagnosis at all) has measurable impacts on mental health, education, work, relationships, and physical health.

And I know that firsthand.

Growing Up in a Neurodivergent Household (With No Language for ADHD)

I grew up with two parents with undiagnosed neurodiversity.

That meant there was a lot of “different” in our house—but no language for it, no framework, and definitely no diagnosis.

My ADHD went undiagnosed for 38 years.

I always knew that social interactions were… complicated. I could do them, but they didn’t feel intuitive. It took me a long time to work out how to manage social situations in a way that didn’t blow up in my face.

My solution?

I built a very high masking strategy.

I became the person who could get on with almost anyone, in almost any situation. I learned to adapt, mirror, and smooth things over. On the outside, that looked like:

• “Friendly”

• “Flexible”

• “Good with people”

On the inside, it was exhausting.

I just assumed that everyone else was as tired as I was after social situations. They weren’t.

How ADHD Shows Up Differently in Girls (And Why It Gets Missed)

Many girls with ADHD are quiet, daydreamy, and compliant—so their struggles are often missed or dismissed

For decades, ADHD in women and girls wasn’t the focus of research. The “classic” ADHD picture was:

• Hyperactive

• Disruptive

• Running around the classroom

• Getting into trouble

Girls and AFAB kids often present differently:

• More inattentive than hyperactive

• Daydreaming, “spacey”, “disorganised”

• High internal distress but low external disruption

• Overcompensating with perfectionism and masking

A major review of ADHD in women notes that girls are less likely to be referred, less likely to be diagnosed, and more likely to be missed entirely compared to boys with similar levels of impairment (Quinn & Madhoo, 2014, ADHD in Women: A Review, PMC4195638).

If you’re quiet, compliant, and academically capable—especially if you’re masking hard—people don’t tend to ask, “Could this be ADHD?”

They ask, “Why is she so emotional / disorganised / inconsistent?”

University and “Smart But Struggling” – A Classic Undiagnosed ADHD Story

I went to university later in life.

It was incredibly challenging, and I couldn’t understand why I wasn’t able to learn in the same way other people did—even though I tried all the “learning how to learn” strategies.

I did everything they tell you to do:

• Study skills

• Time management

• Colour-coded notes

• Flashcards and summaries

And still, it felt like I was dragging my brain through wet cement.

Here’s the part that really messed with my head:

• I could get HDs almost across the board 

• But some subjects just would not stick, no matter how hard I tried

• I would have to reset the entire topic—start again from scratch—to scrape through and pass

From the outside, that looks like “high achieving.”

From the inside, it felt like: "Why is my brain like this? Why can I be brilliant in one area and completely lost in another?”

Research shows that girls with ADHD often start strong academically, then struggle as demands increase—especially with organisation, planning, and sustained attention. They’re frequently labelled “capable but lazy” rather than screened for ADHD.

That was me. Smart. Capable. Exhausted. Confused. And constantly feeling like I was somehow failing at being a person.

ADHD Misdiagnosed as Anxiety, Depression, or “Not Trying Hard Enough”

Symptoms of ADHD in women often overlap with anxiety and depression, which is why so many are treated for the wrong thing for years

Because ADHD in adult women often shows up as:

• Overwhelm

• Emotional dysregulation

• Chronic stress

• Low self-esteem

• Exhaustion from masking and overcompensating

…it’s very easy for clinicians to label it as:

• Generalised anxiety

• Depression

• “Stress” or “burnout”

• “Personality issues”

A 2023 systematic review on ADHD in adult women (“Miss. Diagnosis”) highlights that many women spend years in mental health care being treated for anxiety, depression, or personality disorders before anyone screens for ADHD (Miss. Diagnosis, 2023, PMC10173330).

The problem isn’t that anxiety and depression aren’t real—they absolutely are. It’s that

they’re often downstream consequences of unmanaged ADHD, not the root cause.

So women are given:

• Antidepressants

• Anxiolytics

• Therapy that assumes the problem is “negative thinking” or “poor coping”

…while the core issue—ADHD-related executive dysfunction and nervous system differences—goes untreated.

The Plot Twist – My Sister’s ADHD Diagnosis and My Lightbulb Moment

Everything shifted when my sister was diagnosed with ADHD.

I started researching what ADHD in women actually looks like so I could be supportive of her.

And as I read, I had that creeping, uncomfortable, slightly horrifying feeling of recognition:

“Oh. Oh no. This is… me.”

The social exhaustion. The masking. The academic inconsistency. The constant feeling of being “too much and not enough” at the same time.

When I was finally diagnosed with ADHD at 38, I was stunned.

It felt like:

• Grief – for the decades I’d spent thinking I was broken, lazy, or just not trying hard enough

• Deep compassion – for the younger me who was doing the best she could with no framework and no support

• A massive lightbulb moment – “Oh my God. I’m not broken. This makes so much sense.”

Diagnosis didn’t magically fix everything. But it explained me to myself in a way nothing else ever had.

And it made my life so much easier.

The Mental Health Fallout of Late ADHD Diagnosis in Women

When ADHD goes unrecognised, the risk of other mental health conditions goes up.

Longitudinal studies following girls with ADHD into adolescence and early adulthood show:

• Higher rates of mood disorders (depression, bipolar)

• Higher rates of anxiety disorders 

• Increased risk of self-harm and suicidal ideation 

• Greater risk of substance use disorders compared with non-ADHD peers (summarised in Miss. Diagnosis, 2023, PMC10173330)

When ADHD isn’t recognised, the narrative often becomes:

“You’re too sensitive. ”You just need to try harder.” “Everyone’s tired and stressed.”

That internalises as shame, not “I have a neurodevelopmental condition that needs support.”

Social Life, Masking, and Burnout in Undiagnosed ADHD

Many women with ADHD become experts at masking in social situations—then crash hard when they’re finally alone

Socially, undiagnosed ADHD in women can look like:

• Difficulty reading social cues

• Interrupting or oversharing when anxious

• Forgetting plans or messages and being seen as “flaky”

• Intense friendships that burn out quickly

• People-pleasing and over-functioning to compensate

Expert consensus papers on females with ADHD note higher rates of:

• Rejection sensitivity 

• Interpersonal conflict 

• Risky or impulsive relationships 

• Exposure to emotional, physical, or sexual abuse (Females with ADHD: Expert Consensus, BMC Psychiatry 2020)

If you grow up believing you’re “too much” or “not enough,” you’re more vulnerable to:

• Staying in unsafe relationships

• Overworking to “earn” your place

• Ignoring your own needs until burnout or breakdown

For me, that high-masking strategy worked—until it didn’t. The cost was chronic exhaustion and a nervous system that never really got to exhale.

Late ADHD Diagnosis – Relief, Grief, and Rebuilding

A late ADHD diagnosis doesn’t erase the past, but it can bring powerful validation, self-compassion, and a way forward

Qualitative studies of women diagnosed with ADHD in adulthood consistently report the same themes:

• Validation and self-compassion – “I’m not broken; my brain is wired differently.”

• Anger and grief – for the years lost, the relationships harmed, the self-esteem damage.

• Reframing the past – school struggles, “failed” careers, and “messy” relationships suddenly make sense.

• Improved coping – with appropriate medication, therapy, and accommodations, functioning improves. (Adult Diagnosis of ADHD in Women, 2024, SAGE)

That was my experience too.

Diagnosis didn’t turn me into a different person. It just gave me context, tools, and permission to stop beating myself up for things that were never a moral failing.

The Bottom Line – You’re Not Broken, You’re Undersupported

Misdiagnosis or lack of diagnosis of ADHD in girls and women isn’t a minor oversight. It shapes:

• How we see ourselves

• How teachers, parents, and partners treat us

• Our risk of anxiety, depression, self-harm, and substance use

• Our academic and career trajectories

• Our relationships and physical health

The science is slowly catching up. The systems are not.

We need:

• Clinicians who understand female ADHD presentations 

• Routine screening when women present with chronic anxiety, depression, eating issues, or “burnout”

• Trauma-informed, neurodiversity-affirming care that doesn’t default to “try harder”

And we need women to know:

If you’ve been struggling for years and feel like you’re constantly failing at “basic life,” you are not broken.

You might just be undiagnosed and unsupported.

What to Do If You See Yourself in This

If this feels uncomfortably familiar, you don’t have to figure it out alone.

• Talk to your GP, psychologist, or psychiatrist about ADHD assessment 

• Bring notes about your childhood, school, work, and relationships

• Mention masking, burnout, and how long you’ve felt this way

And if you’d like support from someone who actually understands ADHD, chronic illness, and masking from the inside:

Rebekah (“Bek”) Sutton is a nutritionist based in Perth, Western Australia, specialising in chronic illness, neurodivergence, and trauma‑informed care.

She lives with ADHD, POTS, endometriosis, fibromyalgia, chronic pain, and menopause herself—so when she talks about masking, burnout, and medical gaslighting, it’s not theoretical. It’s lived experience, layered on top of a Bachelor of Health Science in Nutritional Medicine and years of deep‑dive reading into women’s health and neurodiversity.

Bek works with women and AFAB folks who are:

• Navigating late ADHD diagnosis or still stuck in the “is it anxiety or is it ADHD?” limbo

• Juggling chronic illness, fatigue, and executive dysfunction

• Tired of being told to “just try harder” with food, routines, or self‑care

Her approach is:

• Body‑neutral and anti‑diet – no weight shaming, no “willpower” lectures

• Neurodiversity‑affirming – practical, low‑spoons strategies that respect how your brain actually works

• Evidence‑based and transparent – open about what we know, what we don’t, and where the research is thin for women

If you’re sitting there thinking, “This sounds uncomfortably like me,” you’re exactly who she writes for.
