I don't understand how I weigh 124 pounds? I wear 2-3 size pants and small shirts, when I stand my hip bones and collar bones are visable and when I lay down they're really strong. And I don't have big boobs or butt. When I was getting a check up they said I was more on the heavier side but I look skinny, I just weigh 124 pounds. WHY AM I HEAVIER??
