There used to be this mean boy on my swim team who was obviously jealous of me, he didn't want to bully me because I was the coach's favorite so he would bully my three friends, in response, I complained to my coach who then suspended him. He never bullied me or my friends, but he never acted nice either. Just tell your favorite teacher or your principal if you like her/him. If it's better, tell a school counselor if you know one, a friend with authority would be good too. Just remember, your not alone and NOBODY has the right to make you feel like you're less than anyone. About your friends, if they really like you, they won't tease you, if they do tease you, they were never your friends to begin with.
