Welcome to SR.
While I don't have any suggestions... I can't help but notice you darn near posted the same thing I just wrote out. So know at least that you are not alone in your loneliness... as apparently neither am I.
I come to SR--often--because I don't have anybody to talk to in real life. It sounds trite, but it does seem to work. Although I really want real-life friends too... I just don't know how yet. I have similar problems, with the not driving, and the not drinking.
So sorry if this wasn't very helpful, but welcome.
