When I was 14 all of the other kids in school used to call me fat. This really got to me so I started to eat less and less. Now I am 17 and whenever I do a BMI they all say different thing some say I'm a healthly weight and other say that I'm underweight. I dont know which one to belive. I'm 5 foot 7 inches and i weigh 7 stone 12.

can you please tell me which one is correct.I find it hard to belive that I am underweight cos whenever I look at myself in the mirror all i see is someone who is fat.
