The more I think about this, the less sense it makes. Your pdoc was specifically asking how you felt about your treatment. You said you didn't think therapy was the reason you were feeling better and that you thought it was, in fact, the lack of therapy that might be behind the improvement. If that's how you really feel, I don't understand what you were supposed to say. Therapy can be powerful, both as a force for good and for harm. That's the whole point of informed consent, right? So did he want you to say, "Oh yes! I am sure therapy is working!" if you didn't think it was? Or if you had a sense that maybe therapy was making you worse? Seems like some nonsense to me...

Given your unusual situation, I wonder if your pdoc wants an unnecessary amount of credit for agreeing to take you on. If he is feeling resentful and needing your adoration to counterbalance that feeling, then he needs to put a stop to that dynamic pronto.
