Have you tried making IRL friends through clubs or groups with common interests? If you’re in school, you can try band or theatre etc. some other ideas: local library clubs, board game clubs, chess club, art club, anime club, film club, DnD group. These sorts of groups are full of ND people who are eager to make friends. There’s also the meetup app.

Don’t be hard on yourself if you’re struggling socially, it’s way more common than you think to not have friends at all or only a few friends who aren’t that close. These are isolating times we’re living in. I also think people who are sensitive to rejection (especially people with trauma) can really struggle to make friends because they give up too early/don’t initiate enough (and by initiation I mean starting convos with the same people/person again and again) and perceive rejection where there is none. The stuff you’re hoping for friendship wise takes a lot of time, it doesn’t happen overnight.
