Hi I'm 13 years old and I want to lose about 30 or 40 pounds by the end of the school year, but I can't and I don't know why to do. I try to exercise but it's hard cause my house is very small and my parents have trust issues about me going out for a walk or even a trip to the park by myself. I ask my parents to like go out for a walk but they always say no. Wut should I do, I feel so depressed! My calves and thighs are huge and my stomach sticks out. My best friend, says I'm skinny, but I don't feel like I am.
