I am so moved by what you are dealing with because I am facing the same difficulties with my work in T, too. My T has explained my fear of him and lack of trust as being manifestations of the PTSD. Of course we don't trust our T's or believe their views of the world as generally positive! We have our own experiences of the world being malicious, hurtful, and completely untrustworthy.

The hard part is deciding whether we want to challenge that worldview. The really hard part is daring to trust that worldview. Not that I have any answers--I'm trying to do the same thing, and it's terrifying.
