Maybe instead of talking directly about food you could talk about how what your T has said in respect to it and how it makes you feel? I think that is viable. I mean, we do these things because we feel they help us, even if they do not. Have you ever sought out help from a moderated therapy group with a focus on EDs? Would your T be more helpful of you were getting extra outside help? Idk. I love my T, but she once told me that she wouldn't see someone who self medicated with alcohol unless they were also in AA. In a way this startled me.

Maybe it might be helpful to read up on what the various techniques are used by therapists in general to help people in the ED area... then you might know more specifically what you need from your T that he is not providing?
Sending warm wishes your way.
