I need to lose weight as fast as possible.?

I'm 135lbs, 5'8", and 14 years old. These past days I have been gaining weight. I've have starved myself in the past and weighed around 129. And I NEED to get back to that weight. Before I starved myself I was doing daily workouts and that did not help me lose any weight. That's why I resorted to starving myself. I really do not want to starve myself, but I need the weight off and I honestly do not know what to do. I'm not a idiot, I'm completely aware what crash diets and what starving yourself does do to your body. I just need the weight off in a few days, or as quickly as possible. Please help.
