i want to start seeking diagnosis but dont know where to start

for some context ive been self diagnosed for a few years but want an official one for accomodations as i graduate in a couple years (if everything goes right).

even after figuring it out myself after months of research ive been hesitant to see a doctor about it. this is because at a young age i was misdiagnosed with GAD which set back a lot of progress in my opinion. i know this is more common with women so thats why im in this subreddit.

my main question is where should i start? and for other women what was your experience like and what should i expect starting this journey?
