I'm 12 years old and really short. I don't have an actual problem but I'm just a lot shorter. I am 4' 8" and I only weigh 62 lbs. I have a very small appetite, and I try to eat more and better but I can't. My mom says I need to do a physical activity but I hate all sports because I'm bad at them and the people there are usually really mean to me. I don't want to join a sport because the people don't make me happy, which I don't want to have to feel. What are some fun things to do to help me grow, and get bigger?
