I'm so glad your therapist is on your side. There have been a few times that my pdoc wasn't answering and my therapist has called and it always has gotten results. They used to work together so they know each other and generally she listens to him. Once it was just something so simple as I had an appt. on a Saturday at a place I couldn't reach her desk directly so I left a message with the person who answered that I still really needed to talk to her and could she please call me. Except they ignored the part where I'd been vomiting for 2 days and most of the other stuff explaining my situation and left her thinking my no-show was passive aggressive. So he straightened that out and saved me a conversation I couldn't have had.

My favorite call though still was once when I was on short-term disability they were coming up with excuses to deny that were ridiculous and I was starting to need food. My pdoc called them and told them that she would not sign off on my return to work until I had experienced some days demonstrating less stress and that until they were paying me she would be unable to state that I was under less stress because they as a company were making my situation worsen rapidly. A few days later they approved it and shut up.

I think I suggested this before, but maybe you can start trying to get on some pdoc wait lists now so you are left to deal with this idiot as little as possible. He's clearly paying no attention to you at all at this point and you need and deserve better.
