My parents keep making fun of my weight. I've been trying for about a year to loss any bit due to the fact I can't have a separate meal then them I have to bad for you food, and anytime I voice that I want to loss weight they tell me to try, they even say they will work with me on it but the next day it's doughnuts for breakfast McDonald's for lunch and the fattest cut of meat ever for dinner along with fried potatoes. I'm about to the point of taking a knife to my wrist and end the suffering.

Any suggestions?
