Hi, Im 15, weigh 47kg (103 pounds) and am about 163cm. I have a athletic body, and im worried that i might be getting a eating disorder. My mum says its just how im built, and i'll get better. First of all, im scared to gain weight, and go over 50kg. I know im growing, but i dont wont to gain weight. I dont eat breakfast, sometimes lunch, and mabey dinner. I weigh myself, and if i think im getting close to 50kg, i wont eat, and might do some exercise.
