You could see a psychologist/psychiatrist that specializes in eating disorders. Just google where you live and see if one is around. They will help you with the behavioral aspect. You could also see a dietitian if you want to talk about your diet and meal intake. You might find that a center has both available to you at the same place. If you can't afford it, try thinking about the what, why, and when of eating. Document when you eat and why along with what. Then try to figure out ways to deal with those emotions. If you eat when stressed or bored, tired, happy, sad- find a different way to handle it (walk, call a friend, read a book, take a shower, brush your teeth...).
