I too have such a hard time with letting myself feel let alone express anger. I have been really frustrated lately with therapy even though I have the best therapist in the world for me, I had to ask for a 2nd session this past week because of my whirling frustration and I wrote it all out and read it to her - crying the whole time - telling her i am frustrated with her, me, the therapy process in general, all of it, and that i was angry that she didn't have a notification plan in place that i've mentioned here on PC a bunch. Egad it was hard to tell her I was mad about that. Her response was as consistent as always and that in itself was very healing. I'm sorry you're going through this anger stuff too. It sucks. Hugs to you!
