This is why diagnosing should be left to pdoc, and not T's, psychologists or psychotherapists etc.
This shyt really boils my blood.
If she had concerns she should have referred you for a second opinion (but we all know how much T's despise a someone else overlooking their decisions) instead of boosting her self importance and deciding she knew what was best.
Personally I would be out.
And I would find it almost impossible to trust her as I would suspect her of continuously covering her behind.
Which is probably why she isn't answering your questions or concerns.
To worried about digging herself a deeper hole by admitting what she did was crooked.

Sorry your going through this.
Also psychodynamic twice a week for 6 years?...that's ALOT of therapy.
Afraid I smell financial gain at the centre of this one.
But then I am a solid cynic,so....

All the best whatever you decide.
