Volunteering?
support groups?
like-minded social groups/outings?

Try 'meetup.com' No, it is not a dating or hook-up site. It is rather a clearing house of social groups. Search there to find something that interests you. My good friend belongs to one where the members simply meet once a month to do an activity. She has go-karted, skiied, zip-lined, hiked, and even gone to a trampoline club. She has met some great people and I think this is how she met the man in her life.
