This is the rub of therapy, I think. It's all about you changing. And they have little to no incentive to change themselves even if what you point out about them is true.

I am very lucky that my T took a small bit of my feelings to heart and is trying to be more supportive. By far, however, I am the one who needs to do all the other changing. It might work out with this T; it might not.

I am sorry your situation is ending. I hope you can find peace with it.
