Yes, that first sentence... it took me ages to get to where I can actually get it out - and even now, even as recently as yesterday, I had to pause after three words and tell T that I needed a minute to get my breathing in order. But it has been possible to get to where I can get it out, and I am positive that it is possible for you, too. I have sometimes written down what I want to say (as a letter rather than bullet points) and brought it with me to tell T. But then there is the issue of overthinking and editing and changing the words, which I imagine you might also have.

I am glad you got more sessions per week, and that she is flexible about coming more often. May I ask whether you know that she was irritated with you, or whether it was your interpretation? (I agree that the words you quoted seemed a bit annoyed, but I can imagine that they could be said in a concerned rather than irritated way.)
