Sarah, my heart goes out to you because I know I'd feel exactly the same way you are feeling. What your T did IS a betrayal, in my book for sure.

To me it also wouldn't matter if she was extending sessions out of compassion for me (which I do believe was the case).

The point here is that your T completely denied your right to decide for yourself how this problem of limited sessions should be resolved. This was supposed to be your decision and your decision only. By making that decision for you without asking you about it first and by lying to you about what the real situation was she disrespected you. If she'd told you from the start what the real deal was and offered you to extend the number of sessions at the risk of therapy being terminated any time if her superiors find out, then it would've been your decision to go ahead with it or not. If you'd decided to do it, then, at least, you would've been prepared for an unexpected termination and wouldn't have been traumatized by it.

So, yes, she was dishonest and irresponsible. When "compassion" doesn't take into account the realities of the situation and when the "compassionate" person doesn't ask the one they want to help if the person wants the kind of help they want to offer, that's not real compassion to me. It is someone trying to boost their self-image of a heroic rescuer.

Unfortunately, therapy profession is full of those who use it to built the "hero" self-image to make themselves feel good about themselves, which has nothing to do with helping others.

Screw your T. Seriously. I too don't believe that another phone call would make you feel better. And, I also find the fact that it was you, not her who has been calling so far outrageous. She should be the one calling you and she should be apologetic and sympathetic to you if she wants to repair the damage at least a tiny bit, which doesn't look like she does.
