You say your therapist is nice but I wonder if her emotionality (a T crying in session regularly sounds like a lot) is counterproductive and distracts from experiencing and expressing your feelings? It's a bit like she is doing what you would like to and you are doing what she is supposed to (controlling your emotions). Would it be useful to talk with her about what you said here and ask her to be less reactive? You say it does not bother you but maybe it is part of why you can't let go more easily, the focus is too much on her.
