There is nothing really to say here. I think, it's obvious that what happened was very unfair to you and inhumane. The supervisor and whoever else was making a decision didn't seem to care at all about how this would affect you.

I was once fired from an agency (my very first internship place) just because I set my boundary with one of my supervisors, who loved analyzing her interns in supervision. I refused to be analyzed and she got pissed and convinced the admin that they had to get rid of me. Anyway, long story short, the director of the agency gave me 3 weeks to wrap up my cases. So, each of my clients got 3 weeks to process unexpected termination that wasn't my fault or their fault. And, you know what? I thought that 3 weeks was an outrageously small amount of time for people to get a proper closure and that it was inhumane to force me to end my work with them just over 3 sessions.

You didn't get any opportunity to make a closure. None.

While I generally agree with Deejay that a few additional sessions, probably, wouldn't have made you feel much better and wouldn't have diminished your grieve, on some level, I think, being able to make some closure (as imperfect as it might've been) would've made it a little easier for you to accept the loss.

But, I also like the Deejay's idea of shifting your perspective a little. In the sense, to look at this situation as more of a "glass half-full" than a "glass half-empty" way. If you can see and appreciate the value of what you had received during your therapy with that woman more than you can see how she wronged you, that could allow you to see the bigger picture and to detach yourself to some extend from just one piece of it.

I know it is hard to shift perspective when the hurt is raw, and that's okay. It's okay to experience the sense of injustice done to you as long as you need to fill fully validated. But, while you are feeling all that hurt, it would still, I think, help to keep in mind that what you had received in therapy was needed and you wouldn't have received it if not for your therapist's actions, wrongful as they were.

Curse and blessing often come together and, in fact, can't be separated from one another. Sometimes, very painful life experiences are the "price" we pay for knowledge and lessons and good experiences that feed our hungry souls.

I know that almost every person, who has wronged me over the course of my life, knowingly or unknowingly, and every experience that has traumatized me also has contributed into my personal growth
