I apologize that I don't bring 'good' advice with me only anecdotal! ...There also the community adhdwomen@lemmy.world, someone there may have some hepful suggestions!
I'm older, wasn't diagnosed until well into adulthood, also female. Of course, it didn't help that it was deemed medically impossible for girls to have adhd back when I was growing up, for getting proper diagnosing.
What really pushed me over the line to finally get diagnosed were the adhd communities here and elsewhere. Some of the silliest memes will sometimes have some great conversations within the comments. Posts with articles others found interesting, various answers folks have for questions asked... I have learned a lot, and get a lot out of, reading through other's experiences, and getting some feedback on my own.
For me, I retain more from an article posted and then that 'live' conversation, vs. a book that might present multiple topics, that I then start researching one of, then fall down some random rabbit hole instead of continuing the book in any sensible amount of time.
Best of luck to you, in finding the resources you're looking for, and all your journeys!
