I wouldn't say overly introverted self conscious bastard. You're obviously not interested in doing the same things as they are/feel like you don't fit in and that's fine. But your post came off as though you think you're better than they are, which you aren't, you're just in to different things. It doesn't make you a bastard but it doesn't make you mature.
Sorry, I tend to give off the wrong messages. 
I just feel really bad/left out because I want to be alone when they always encourage me to not be. I have friends, of course. I would never want to think myself as better. That would really shame me for my entire life. Thank you for your opinion, by the way.
