Im SO Sick Of Feeling Like This?

alot of people think im this girl who always has an attitude over everything . they always say how im a b*tch , and how im always taking my anger out on them . but then they always turn around and still wanna be friends . first of all , i know i have anger problems . i feel like i cant change whether i want to or nt . i get so sick and tired of people saying ' i dont like her cause she has a bad attitude ' . im really sick of it . to get to the core of it , im a 13 year old girl . i absolutely hate my life . everybody always expects me to be so excited about living , but inside , i would kill to have my life taken away and replaced . i feel like life is useless . and all this stress with things such as home , school , and social life has created all this anger inside of me . im not saying i have the worst life ever , but its pretty bad . and it hurts so much when people constantly talk about how im always mad , or as they'd say 'bipolar' . im really tired of this . and im called stubborn because i cant change my ways . and im supposedly 'mad at the world' . and i only recognize 'negative things' . i cant take this anymore . i swear i want to kill myself right now.. did i mention i cut myself . like i dont even care what good things await me in my future . i wish i wasn't even born . i keep getting these suicidal thoughts in my head . and right now , i might just listen to them .
