Learning.........I am just guessing, but I would imagine a therapist can help you figure out why since most overeating is emotional in nature, there is a trigger to it. I do think it is wise to only deal with one major issue at a time........so put this one at the back and you may find as you continue to heal, that this problem is solved as a result of solving other reasons that brought you to therapy in the first place. I don't know for sure if it is that easy, but I do know that all my reasons for being in therapy are interrelated.
