Rather than deal with what your pdoc said in a rather reactive way, why not try a different approach, more of a proactive approach? How about talking to your therapist about exactly what your pdoc's concern is. Get your T's take on your pdoc's perspective. That would be the first thing to do I would think. Perhaps your T could consult with the pdoc, maybe on speakerphone while you are present, so you can all three be on the same page about your goals and treatment. I suspect once they talk it will put your pdoc's concerns more at ease.
