I let my anger out at T when he messes up and I think he deserves my anger. (like when he forgot about my added on session and such) I email him with it...I'm not there yet showing it in person. I've sent angry emails accusing him of such and such and def using cuss words though not directed at him, and he always responds calmly. (suprisingly!).

I think if I would have specifically called him names and threatened him, he would refit sly draw boundries. He told me of this one guy he had a long time ago in his practice who was very very angry man and he had to terminate because he was constantly threatning T and I guess making him scared for whatever he was doing...

My T acknowledges I have lots of anger just from my emails cause I sure haven't shown it in session. I hope that you are able to let T see some of your ante or find out what's accetable with her re: expression of clients anger.
