How does she usually interact with you during sessions, does she bring things up or do you? Mine pretty much doesn't bring things up, but waits for me to do that. It doesn't meant she thinks it's unimportant, though. I think it's an approach to therapy that some have (and in only this one case, with this therapist, does that work for me).

I'm guessing she'd act the same way with this information as she has with you in general. If you have a hard time finding your way back into it, and she is waiting for you to say something, all you have to do is ask her for her thoughts on what you wrote, that it's hard for you to bring up so you're handing the ball to her to get things started.
