I'm 16 years old. I used to be heavy during elementary school, but I lost weight when I was 13. I did that by not eating and starving myself. I made myself throw up several times and cut my arms and legs almost every day. My parents constantly told me I had to lose weight, and it wasn't helping me feel better. When I started going out more, it was gone unless something triggered it. I decided to go vegetarian at 14. Since then, I've been pretty active, but had a hard time doing cardio because of my breasts (currently an F cup). Doctors told me to avoid running and jumping. During the last 6 months I've been going to the gym, lost a lot of fat and gained a lot of muscle mass. I gained 10 kilograms, but I look leaner and more toned. I've been eating healthier than ever. Two days ago I started having severe back pains after doing crunches, and my parents drove me to a hospital.since then, they constantly tell me I'm too fat, unhealthy and lazy. I feel so unattractive and disgusting.. I don't want to eat. My parents do this every time I start feeling better about the way I look and I can't stand it anymore. I'm terrified of going back to my old habits. But no matter how hard I try to make them understand how much they're hurting me, they never stop. What can I do??
