I think you know exactly what the situation is, that a new pdoc might be in order. The only thing I have to add is that if you chose to go this route, a lot of pdoc's, especially good ones are booked 1-3 months in advance, as a new patient you might have to wait 2 or 3 for an appointment. So, unless you want to have a problem with getting your meds filled, don't 'fire' the old one till you are hooked up with a new one that you think you will like.

Therapists are a great way to vent, and of course, PC forums are as well. Good luck.
