I wouldn't bother keeping up those social connections from what you've described of them here. Doesn't read like they're the sort of people you need to be around.
Maybe the community support place just wasn't the right crowd for you? Maybe seek social interaction in a quieter crowd, maybe academically, in a course or class? I don't function socially either, so I find classes or interest groups are the way to go, as there is a topic which interests me and everyone else there so we have something to discus, there is a purpose (you're learning something) and an understandable structure.
You don't have to work to make friends. Really, many people in a workplace have nothing in common with each other, they're just there to make a paycheck. I'd go for interest groups, hopefully in an atmosphere where people are going to be more accepting and patient.
