while I made some really good friends at my support group, it was not a meetup kind of group, it was structured and sponsored, I also made the mistake of getting involved with one of the men there and it turned out REALLY bad and I ended up with my first ever psych hospital stay that lasted 2 weeks.
he had schizotypal personality disorder and after hanging out together for about 2 months as friends we had an intimate encounter...3 days later he became someone else, mean, scary and angry. I unfortunately had been manic for about 7 months by that time and I crashed into a depression and suicidal thoughts but he was the trigger. I haven't been back to a meeting since 2013 but for other reasons. the friends I made in 09 don't go either.
A good support group is good for just that, and possibly making some friends, but it is a terrible place to meet someone you would want to be involved with. at least that is my experience and that of a couple of other people I knew.
