Echoes, do you think it might help to write out exactly how you felt and are now feeling and email it to him?

I'm only suggesting this because I know it would help me- I realize it might not be for everyone. If I were in your shoes, I would like my therapist to be able to understand what happened from my perspective, and email would relieve the pressure for me and allow my therapist time to think about it and take it in before he needs to respond.

It sounds good he's talking to his supervisor anyway!
