So glad you found a decent therapist, as that makes a world of difference. As far as friendships go, try your local theater group. You don’t have to act, you can build sets or any number of things. But a lot of theater people are ADHD, and as a group tends to be non-judgemental about things. If not that, then yoga or some other type of class. I have found that sharing a hobby can create wonderful friendships.
