I got ripped pretty hard in school because my last name is easy to make fun of
No idea what your last name is, but I doubt its worst than mine is ;)
My advice is don't seek friends. Be sincere with yourself, if you don't like people around you, people will feel it, start liking people, and people will like you too.
This is quite important. Stay yourself and let friendships grow. Don`t force them.
Seems like your main problem is confidence, but good news! The more you practice the better it`ll go :D So just start making conversations (little tip: don`t start with the "popular kids" but just with the normal kids. They are often much nicer to shy people)
