I'm sorry you're going through this, but really I think this is an opportunity. Current therapist seems to not want you as a client anymore (that line about drawing conclusions), and you have another therapist lined up, who won't see you unless you quit the first therapist.

The new therapist would be your support. At the moment I see nothing supportive about your current therapist's behavior. You are better off with no support at all than with an emotionally abusive therapist.

Ever had a bad romantic break-up? Sometimes, you just have to walk away.
