Help.. i'm very sad! VERY!?

Go to your parents and tell them what is going on. If they won't help go to your school guidance counselor and tell him/her what is happening. Also tell your most trusted teacher what is going on. Don't let them pick on you however...you have to put your foot down, but don't resort to violence. If things get out of hand get a teacher/principal to help you out. Find people who you can trust to help you, somewhere out there someone does want to help I know it. Highschool can be a brutal place and kids today are a horrid lot. Also taking up a martial arts might help your anger out...not for the defence or violence sake but to ease your mind when bombarded with negative peoples words. It can be a good way to help your mind deal with managing that anger you get from schoolmates.
