The key is to be comfortable with it - I was fighting the same oh-my-god-im-socially-poor thing but then I realized I don't happen to enjoy being in company of people not very close to me. I've since embraced it - I no longer view that as some kind of deficit I need to compensate for. And you know what that has made me better socially. It might sound weird but when you drop the whole expectation burden, when you no longer try to fit in, you become yourself and other people naturally like that.
