AM I SUPER DUPER SILLEY BILLEY FAT?

There is more than likely no answer. At your age your body is not at all concerned with "how flat your stomach is". Health is far more important. As long as you are exercising and you eat fairly well, you have nothing to worry about. You are in the process of "growing into" your body. Depriving your body of what it needs by dieting, etc, is a good way to cause yourself developmental delays and health problems. You are fine honey. Good luck.
