I'm overweight, starving myself, and crying because of it.?

Every day i look into the mirror and i'm so upset. I'm a 14 year old, 5"8 female and i weigh 76 kilos. I'm overweight, and i walk (because of school between classes) everyday. But i don't really do any other sport, since i hate sport and nothing motivates me to excersise. I don't eat breakfast, i don't eat lunch, but as soon as i get home i'll eat microwaved stuff, bread, junk food then i'll have dinner and its so bad for me. I'm sick of this. I saw the counsellor and all she said was that i need to eat in moderation throughout the day. She also said that i'm hardly depressed and i'll be fine. (she freaked me out). I didn't tell her how daily i'll just sit and cry, and uncontrollably think about dying and killing myself. My right arm is full of cuts and blood stains and i hate how ugly it looks. I hate how people tell me i'm beautiful and i know they are lying. I've honestly got no idea what to do with my life anymore. help?
