Yalom aside, I (of course) think you should talk about this with your therapist. I don't know if you already talked about the straight revelation with him (I know you were going to), but it can't hurt to talk about it again because I think this is important! I know what you mean about the emotional part of your brain thinking for you (been there, done that)--make the saavy social worker part of you tell your therapist everything you said above...about this Yalom essay and what you're worried about him thinking when you sit there with him and about using food and everything else.

If he's not an asshole and he's good at his job, my instinct is that he's going to reassure you. And if you think he's lying...tell him that, too! I think this could be really good for you!
