I'm so sorry to hear you've been through such a bad termination. It sounds like she got scared, didn't know how to work with you through your transference, and chose the easy (for her!) way out. Most T's I know require the client come in for at least one session dedicated to the termination process and your T didn't offer that even when you asked for it. It sounds totally unprofessional and like she was taking care of herself more than you (in session I mean) and terminating more for her own sake. I agree that a good termination needs to be given the necessary time to process things. Actually, the best Ts I know wouldn't terminate right away in the middle of such intense transference.

On the other hand, it's also true that you don't give much detail about what you were saying to her about the transference. Were you saying or implying anything about acting it out? Even so, even in case you might have done that, her inconsistency and sudden decision to terminate without even talking about it still strikes me as odd and unprofessional.

Just know that there are many good therapists out there. I know it must be very difficult to have gone through this with someone you probably trusted with a rather vulnerable part of yourself, however you could also take this as an opportunity to find a better therapist. I know it doesn't seem to be something positive at all right now and perhaps you don't really feel like trying again, but even if that is the case, in the long run I really think this will have been better for you than if you'd had such an experience later on, with more attachment and vulnerability going on in your therapeutic relationship.

On the bright side, it sounds like you have quite a good grasp on what therapy is ad how you can benefit from it, as well as a healthy attitude about asking for what you need even when things aren't looking well (such as asking for one more session to process it). I wish you the best of luck in finding a great T.
