QHow do I conquer my addiction?

Just like an alcoholic I am completely addicted to food. Fast food, dounuts, chocolate, cheetos, pasta you name it. I want it to stop so badly. I literally feel like I'm starving even when I am not hungry, it's like a mental feeling of starving I can't explain. Please help me if you can. I don't know what else to do. Every morning I wake up and say, 'today is a new day and I will not overeat and I will not eat fast food.' but as soon as I pass a fast food joint or have a feeling to eat, that whole thought process goes right out the window. I tell myself that I need to just get through one day at a time, but I feel like I'm getting worse. My overeater annonymous self TAKES OVER. Please help!
