I just wanted to say... my teacher was having a conversation with me once, after he knew I had depression. He is a bit of a loner too... the way he put it, is people like us don't HAVE to be social. If that's not who we are it's not who we are. But even if we isolate naturally everyone does need a friend or two. I guess it's more about being introvert but still having some sort of people around you, making the social life fit YOU, not fit to it.
