Something that has helped my sanity a lot: try swing dancing if you can find a local group. It's surprisingly full of other people who have social problems but are friendly and welcoming anyway. The dancing gives you something to talk to people about and I find it to be a huge mood-booster for me whenever I can make it out.
Many dancers struggle socially, but they have an easier time on the dance floor because there's not much talking while you dance and you have something to talk about when you're not on the floor.
Other forms of sports or dancing might be helpful to you too, for similar reasons.
