hi, i've been so stressed recenty am 15 years old and i weigh about 7stone. My friends and family have been constenetly telling me that i am underweight and that i need to eat. I never eat in school and rarely ever eat breakfast, when it come to tea i never finish a full meal, but for me i feel i eat loads, i look in the mirror an just see fat some people say am just being stupid so i never talk abt it until now. i dont know what to say or do to keep everyone of my back, i know it is easy to just say eat but whenever i do i feel realy ill and sick.

Any idea's what could be wrong :( ?
