I think that I'm overweight, but all my friends disagree. At one point, I was near anorexic. I've tried all methods of losing weight from exercising like a fucking animal to dieting. I even stopped eating for three days and only started again when I was so weak that I couldn't get out of bed. All of these were of no avail, and I still remain the same weight. I don't know what to do, and I need some advice.
