I'm in the same boat, in my 20s and just moved to a new place. I was looking on line for drawing groups and I found a figure drawing workshop run by an artist in her home studio. I'm usually a really shy person, but I had a fantastic time because I was surrounded by people who were similar enough to me that we showed up to this workshop.
Figure drawing might not be your thing, but I'm certain there's a group doing a hobby that you like. Try one out and if you don't click with the people try another one.
