I'm sorry you're having a problem with your ED now. I agree it would be best to have a T knowledgeable about EDs. I don't understand how your current T could say she specializes in treating them if she just tells you to "eat" without addressing the underlying reasons why you don't.

I wouldn't rule out "soothing voice T" though. You can ask if she has experience with EDs.

I would also suggest being sure an ED T meets your needs in the other ways you've discussed.
