Just one idea but join a couple of community groups which do gatherings. Might or might not be up your alley doing volunteer community service which will give a person a sense of reason, a very therapeutic thing, but Friends of Bryan Park is one that does regular park cleanups.

Do a few VCU games and sit in The West End of the Siegel Center, screaming at a game can be a good way to constructively let loose some steam and you'll definitely meet people in that wild group that sits over there. There's one coming up Wednesday night at 7pm vs Vanderbilt. It's gonna be a wild one. If you're iso a quieter athletic experience, do a UR Spiders game and wear a red sweater vest and bring a knitting needle.
