It is hard to say what your next move should be here since I'm far from where I need to be with my T, but my intuition says tell her what you're experiencing. I would prob start by saying at the very beginning of the session, "there's something I really need to talk about but I'm not sure how." This has worked with my T in the past.

I've talked with my T about not wanting to waste his time, that he needs a break from me (since I show up every single week ad nauseum) that my late evening appt. must really annoy him, on and on and on....I'm not sure how to stop worrying about what my T thinks or feels. It's pretty rough....
