How do I go about making new friends?

I’ve always been a girlfriend kinda guy, but as you may have seen, I’m newly single. I’m very shy and have trust issues, so I don’t know what i have too much to offer. I live in a college town and I’m not a very big drinker, so I spend many of my nights doing absolutely nothing. I know I have to find people interested in the same kinds of things I am, but I don’t see any place that has social groups or anything like that around here.

I’m totally lost here guys and gals, what do I do?
