Somebody Has To Stop Bullying

OK. I’ll tell the short version. I’m 13 years old and 170 cm 64 kilo. (And I’m from Turkey). So many people bullied me and they’re still doing that. Joking about me, calling fat, ugly and more. I sucked at my lessons because of them. I’m talking to myself and thats insane. I have a normal kilo but I’m not like "Victoria’s Secret Angels" so I’m trying lose weight. I’m always (at home, secretly) crying. At school, no one cares. At home my paremts already have no idea about I’m crying. I’ll go to hospital for my problems. And I know that bullying has to end. Jokes should be funny but they’re not.
