Someone told me that they binge or overeat because they don't feel they are worthy of anything better, and that they are punishing themselves. That boggled my mind. I overeat and binge at times to get that "full" feeling, and I will even say that at times my mindset is that I just don't care.
I think you should take your time with the weightloss, and try and use tools to help prevent you from going into the binge mode. As a food addict, that could be keeping your insulin consistent, not have binge or trigger foods in the house, always having a back-up food nearby, not letting yourself get too hungry, etc.
Just realize that you are an important person and you have your own free will and you don't have to do anything for anyone else, or because anyone else says to do something, or guilts you into doing it. You are your own, individual, and unique person, and staying healthy and happy is one of the most important things in your life.
