I understand how you feel. All of us feel lonely sometimes particularly if we're not drinking and other people are. I think in terms of making friends, people respond to a large extent to the signals we send them. I had to work hard on that in order to improve my social situation. I have stopped going through life thinking I deserve a friend and I'm being rejected. I'm more inclined now to think about what would make another person happy - how can I do them a little favour or pay them a little complement.
