I personally like to use specialists for everything vs. trying to make it work with one person because I like them, so definitely think this is a good approach. I had an eating disorder when I was young and an addiction later, and these things definitely require specialist knowledge and practical approaches IMO because lifestyle/habit changes and learning new ways to impulse control are necessary. Could you perhaps take seeing the food T similarly to seeing a doctor? People get anxious about seeing doctors as well (I certainly do) but it can be approached as a more focused, solutions-oriented project then. You can still integrate working on this into your long-term therapy as far as the emotional aspects go.

Have you ever tried one of the free peer support groups for binge eating? I never used any for eating issues but was definitely my preferred support and source of practical help with addiction. It was much better for me to discuss those things with people who had actually experienced and overcome them, get tips, be able to reach out in an unstructured way etc. I definitely found that peer groups of of that sort were far more expert and resourceful than therapists and those were the people who understood the emotional elements best. I also liked the groups because it provided variety vs. just one person's experience and expertise.
