"stern" and "laid into me" would terrify me and not work. I can understand your anxiety and apprehension about your next session. But any frustration she has is her issue not yours and she needs to keep that in check. In the many many years I have been with my therapist she never makes me feel pressured. I can go and see her and talk about WHATEVER I want to talk about and I can talk about it over and over and over again. And she has told me I can talk about it until I don't need to talk about it anymore. If it takes a few sessions or a few weeks or a year. She says it is my therapy and my time to use as i wish.
