man, dont, if u havent already, life will only get better, it feels like u've hit drop bottom but just think about it, u wont get out of the situation that your in unless u try to aviod these situations, tell your parents that u'll run away or sumthin, and if U ABSOLUTLEY feel u need to do just that, i say do it, change ur life, and if ur parents care about u they will send out ppl to find you, then u would know they care about you, confront the people at ur school, do watever u can to NOT KILL YOURSELF. my sisters friends sister killed herself and now there whole family is *beep*ed up so dont make this happen to u.
man, just try not to do it... i read all of wat u said and it sounds pretty rough, but, u can make it better
