Girls who grew up with undiagnosed ADHD often become women who:

Live in constant fear of disappointing people and get anxious when someone's upset with them.

Are so used to feeling like they're the problem that they assume everything is their fault, never trusting themselves enough to consider that someone else might be.

Over-explain, over-apologize, and overcompensate because they've spent a lifetime feeling like too much and not enough all at once.

Build successful careers but secretly feel like they're failing and worry they'll be found out.

Lose their footing the moment structure disappears, like during maternity leave or while staying home with kids.

Stuggle even more when their hormones shift during perimenopause, and spend years trying to treat the wrong thing (anxiety, depression) before finalley discovering it was ADHD all along.

Can we talk about how people get overstimulated, and it's mistaken for anger?  No, they're not angry-the TV is way too loud, the dryer's running, someone's mowing the lawn, the phone won't stop dinging, their shirt feels too tight, their hair isn't sitting right, and there are crumbs on the floor that they can feel under their feet.  They're not mad, they're just overstimulated and just need a minute to pull themselves together.  Dr. Fatima Fizwan
