I experienced something similar. I would always plan before my appointment, making a list of things I want/need to talk about. But then I would get there and just freeze. I had a hard time initiating. I think there was a small issue with my T expecting me to bring things up and me wanting her to bring things up. But as it has been said, they can't read our minds. Sometimes, I feel like they tread lightly because they don't want to push too hard.
What I ended up doing was having a conversation w T. I said that I have a tough time bringing things up and told her I think it would be beneficial for her to bring things up and ask directly. I told her she didn't need to worry about pushing too hard, that I was capable of saying no if it went past my comfort zone. I mentioned that I made a list before hand (mental or typed), I started bringing the list with me that way when she asked what I want to talk about she had a heads up that something was on my mind, and I had a guide so I didn't blank.
I hope this was helpful. I am sorry that you felt T was scolding you in a way (even if she wasn't). I am very sensitive as well so I get the feeling.
