This is my opinion and what I wondered: Growing up or in your other relationships did you experience abuse? Did your eating disorder start around then? Was their violence or chaos?
I used to be very overweight and was an emotional eater. I was not food addicted though. suffered abuse as a child and abuse in some relationships. My eating was always a way to subconsciously make myself "unattractive" (not the truth but it was my truth) It was my way of hoping that a person would leave me, or make the decision to break up for me and in some cases being bigger made me feel like no one would want to hurt me. I do not know if you feel that way but I wanted to share my experience. I am no longer overweight but that involved gastric bypass and 16 years of therapy and medication- not an easy process.
