Weight problems? - pinky weight gain pics

Hello everyone I encounter problems. I am a girl of sixteen, the 5'2 and weighs about 85 pounds. I just started PE at school and we have to weigh every week to watch our progress. I am fairly out of shape and the teacher always makes me laugh too tired too quickly. And yes, all the other kids in my class that I'm anorexic, I'm not, I'm happy with my body image, I do not think I need to lose or gain weight. I want a girl usually "little bones" when you do. I have the thumb and little finger around my wrist and knee. What should I do? I was never aware of until this class? If they are right, I gain weight, if so, how?
