Hi, it sounds like a call to the shrink is what part of you wants, and part is too scared,angry, or too 'something' to take the plunge.
I'm seriously trying not to be patronising but your situation is serious and I agree you have little to lose, and maybe something to gain.
Can you email the 'shrink'?would it be easier to write than speak?
Maybe send something like what you put here, the bit about not wanting to phone.
There's a lot of pain in this post, the 'shrink' should recognise and respect it.
Best of luck and I hope you can find some sort of peace.
