I'm the same way, I eat ALL day long and when I dont..LOOK OUT! I'm trying not to rely on food anymore it was hard at first but then I found a hobby. I love to draw and of course I like clothes...im a girl. SO i started designing clothes and soon Im planning on starting a website....Just finding a hobby to keep your hands busy and your mind off of the food will help and its a good way to express what you're feeling at that moment. Hope that helped.
Cheers!
