Um, I've read the letter and it is succint and concise to me. It would appear that the T outlined expecatations and barriers repeatedly and you crossed them. I would agree that this then is more than grounds to terminate your working contract.

Look into DBT or CBT. I've had excellent results. Perhaps a group situation might be the most appropriate.

Speaking of Behavioural Therapy, sit down and give a long look at this whole situation. What evidence do you have the T is behaving inappropriately? What evidence is there they haven't? Similarly look at your own actions and ask what was perhaps positive or contributed negatively to the situation. What then seems to have been the most likely occurance? Consider then what you can do the same next time around and what you might wish to avoid or tweek. Make sure you then form your own expectations, limitations, and barriers regarding your next T/patient relationship.
