I've done journaling off and on and shared it at times with T's. I'm not sure what reaction I was looking for, maybe it was "let's talk about this thing you raised in your journal", but that never happened. My current T has a couple of times made vague references to something I've written, once reading me a quote from a Buddhist text that she thought related to it (it did). They have always told me that they read them and thanked me for giving it to them, so it didn't go unnoticed or unacknowledged. My current T still sometimes refers to the 5 or so things I once said I wanted out of therapy.

I think that the T's I have chosen have been of the variety that do not believe in telling clients what they should work on, so they wouldn't be the type to say, "let's talk about this thing you raised in your journal." I would probably freak and refuse to do so if they did, because I like to be in control of my therapy sessions and in starting the session itself.
