I'm only 12 years old and im gonna turn 13 in a few months and every year at my school for some grades, we go to the pool. the problem is, im really uncomfortable with my body. i even hate it. i weigh probably about 130 lbs but i just dont look like it. is there a way to lose 30 lbs in a month? if so, please tell me how :( i wanna change my body and not feel insecure anymore bc whenever i look at one of my friends body, i get more insecure and i cringe at my own body.
