Hi del12!
I would encourage you to go ahead and write down all of your feelings about T, and why you quit. That way you aren't just waiting for someone to call before you express yourself.
Then, next week with the new T, you can bring your notes if you want, and share why you quit with the old T.
Sometimes I find just getting the words out of my head and onto a piece of paper is useful. Otherwise I have a tendency to keep the dialogue about what happened alive in my head.
Hang in there, and I hope the new T works for you!
