There is a common phrase many people learn as a kid. Sticks and stones may break my bones, but you're a loving pusillanimous individual. Oh, wait... something like that.
But seriously, these are common problems most teenagers are faced with, you just have to learn to deal. It's not our fault you've had stuffty times at school, so don't take it out on us or you may come off as sort of an starfish. Find your own way of coping with anger, but don't bring it down on other people, that's how you lose friends.
