I'm 17, was anorexic about two years ago, and haven't been able to gain much weight since. My dad was super skinny and tall as a teenager. I'm very cautious towards losing weight, but I'm in Body Toning, as well as two movement-oriented Spanish classes. I'm somewhat athletic and very flexible. I have a lot more muscle than fat, which bothers me, because muscle weighs more. I need to know if I need to gain weight, or if I'm healthy. I don't know what other information is neccessary...
