You could look for local Overeaters Anonymous meetings.  You can also get a safe food plan from a doctor.  This will let you know what your body needs.  OA is great for the emotional side.  You have to deal with the deep rooted reason as to "why" you eat.  You need some type of emotional support.  It's too hard to do alone and the self doubt and emotions that made you turn to food in the first place will continue to hurt.
