Some of what you write about your time with this therapist was true for me with my ex-T too. Before I started therapy I was sleeping really deeply through the night every night. For most of the time I was seeing my ex-T I slept badly and the lack of sleep had quite a negative impact on my life at times. I have a new T who I've been seeing for 7 weeks. I gradually started sleeping again since starting to see her. I was attached to my last T, but I think I always felt insecure. i have a lot of emotion around the other therapy, which I think is really emotion from my childhood, my new therapy is not about leaving that behind, my T has a positive attitude towards making it useful for me/us. I kind of feel that ex-T brought the emotion to the surface, and new T is going to help me with it.

I hope you manage to find some peace.
