I Can't Stop Eating

God, I dont know what's wrong with me. Food is just to good. It's not a comfort as much as it is tempting. Its had a serious effect on my weight, starting from when I was a kid. I'm huge now, and I know its unhealthy and bad but I can't stop. I keep shoving in candy bars and chips and snacks. I eat behind my dad's back, hiding wrappers and boxes that he eventually finds. I eat at work, I eat McDonald's for lunch, i get Taco Bell after school. I eat breakfast but it's never healthy. I can't stop, it's almost like I'm addicted to food.
