^ oh your only 17 don't worry about it as you mature things change. I was exactly the same at 17 really couldn't socialise with anyone had no friends either the world was a lonely place lol.
but it gets easier as you get older trust me , you just need to find people who are like you.
I was quite mature and used to act like a grown up lol so I never fitted in with people my age but I've noticed I fit in more with praticing people and they're so much more nicer and friendly.
we can have a good discussion about Islam

try and find praticing people to hang around with. I know that feeling of being different from everyone else it's not easy but don't think your alone.
