I guess I have problems with friends, too. I find it hard to trust anyone (because of a friend who 'ditched' me) and expect everyone to leave. I haven't made it easy on myself though, because I've never stayed in the same place for too long since adulthood (uni, then moved, then home, then moved abroad, now home) so I always have friends in different places and then I leave.

Are you sure people don't like you? That might be a self esteem issue, you assuming people don't like you. Even people who aren't great socially are still likeable! My brother has a friend who's a little 'odd' socially, and some people find that hard to deal with and really don't understand him... but I think he's very interesting and I like him, and he has a good group of friends too who are also 'odd'. What I mean is, not everyone will like you but not everyone will dislike you either, you possibly just have to find people who 'fit' you...? I know it's really difficult when you are depressed though, whenever I have had bouts of depression I totally isolate myself and it's hard to keep hold of friends that way.

Maybe in a support group, or something similar, you could find like-minded people?
