I also want to write a letter but new T has said that she will not hear me if I complain about her or write to her. I need to work on that for me and not just to feel heard.

I ignored my intuition on her lateness and flakiness because I believe I had some transference. I let it go too long and feel some relief although I miss her

Anyway, I wish you lots of healing. You are valid to feel anyway you wish about the ending and especially to feel hurt and abandoned no matter how ex T spins it.
