Sorry she's being such an *** about all of this Myrto. It kind of seems like she wants you to quit. The first thing a therapist should be is consistent and she clearly hasn't done that at all.
I wonder if it would help you to speak to TELL: Therapy Exploitation Link Line about the way you have been treated. You can do so confidentially, anonymously and it is free. They will offer you all the support they can. I found them useful for processing what happened with T1 because they were completely on my side, which my T had struggled with.
I don't think there's any therapeutic value left in this relationship. I hope you can move forward in a way that works for you.
