You say you don't want a hobby, but this is how you meet people and make friends. Climbing is a good one. Improv and artsy things like that attract funny, fun people. Athletic and artsy activies tend to attact the sort of people you're looking for (probably). Working out has great effects on your mental state as well, if you aren't doing it. Also, make an effort to communicate with people and hang out. It's hard and takes a while to break through. Once you make a strong friendship with one or two people, you'll start meeting more. It's absolutely not impossible to get into a good friend group. You could sell all your stuff and work from an RV. You could move to East Asia. You could get a more socially engaging job. Try lots of stuff until you find what you want. What are you working for? If you don't know, figure it out.
