Join a club! Having a group of people you see every week that are happy you’re there is what got me out of my worst depression. I’m in a run club and organize a mountain bike club, but if that’s not your speed there’s lots of others. An improv club/class will probably give you incredible social skills. But there’s roleplay clubs, book clubs, bowling/league night, kickball, knitting, and probably a bunch I can’t think of.
