so i am a girl of 13 years old. i am a little over "5 8". i am pretty much the tallest of my class. i weigh about 120 lbs, but it fluctuates. a lot of people have been telling me i should be a model. i find it flattering, but i don't believe them. i have been having issues about my weight for a long time. ive always wanted to be thinner than what i am. i eat healthy fairly healthy for my age. is that i could there anything that i could do to lose weight? i forgot to mention that i like to exercise about 5 times a week. i enjoy to swim, run, play volleyball and basketball.
