Hi ADD and things that are going on are hard to handle at any age.
But when you find these things at adult ages its even harder.

Don't give up on her. Go out and look for specific books on adults
with add. It should be able to help you.

I'm also guessing the anger issues are coming from having the ADD and
not being diagnosised for so long. Medication if its the right one should work when its the right dosage.
