I had the gastric sleeve surgery done in October 2013 since I was nearing 300lbs. I have lost 113lbs in 6 months during my senior year of H.S. I am now 20 years old with the body of a much older woman. My breast sag (former Full B cup, now an empty cup) along with my upper arms. I sweat under my breast and butt cheeks, which also sags. I have exercised vigorously to try and tighten everything, but its getting to the point where I am hurting myself. I feel like my weight loss didnt mean anything...
