I personally would take out the stuff you are guessing about, ex why she is doing what she is or why she might have counter transference problems.

I would stick to the facts only, you have a huge case going for you. Going for what, I am not sure, personally I think you should find another T. She isn't going to have a sudden epiphany that she did anything wrong. She started off being defensive and is continuing to offer more of that. I can's see that changing.

It is almost like you are wanting to take care of her instead of her taking care of you. I really think this is a bad T, it shouldn't have to take a client to tell her that her excessive cancellations are unprofessional and can leave a client feeling bad. You shouldn't have ever had to speak up in the first place, she should know how to do her job already.

She is already telling you that you can't fulfill your needs because she can't be consistent or reliable as a therapist and her past behavior shows this too. In fact she doesn't think she has done anything wrong, she thinks all T's in private practice does this, so she isn't going to change.

As much as that statement must hurt to hear, I think you really need to see it as a form of truth, her truth of how she is. Unless you feel you can still deal with her cancellations (she isn't going to change) and her defensiveness (that is her personality), than you should move on. Stop wasting anymore time with someone who can't really help you. It isn't you anyway, it is HER. It is sad and I feel bad for you and I hope you will allow us to help support your through this.
