Emergency lose weight?

that's it. See i have to lose 15 kgs and i have till may 15th. I swear i can't even look at myself in the mirror any more because i disgust myself. I have an elliptical stepper. And 3kg dumbbells and a hoola hoophoop. Please or i'm really scared i'm gonna start doing anything to become thin. Ryt now even the idea of food repulse's me . Also i cant do anything outside the house. Let's just say i dont live in a very nice place.
