I am 18 and 5 foot 4. I start college at Mississippi State University in the fall and i want to be able to control my eating before i go there. I am a level 9 gymnast but because i am busy getting ready for college im not getting as many hours as i used too, and when i go to college i will mostly be coaching instead of actually doing gym. The most I have ever weighed is 120 and i was freaking out then, now i'm down 7.5 pounds and keep getting stuck at 113.5 for some reason. i want to try to be down to 105 before August 11th when i go to school.
