Yes, I have done this and it has truly helped. One of the biggest ways it has helped me is that in the past, I would write out what I could not say in a session to my T and now, I am able to say it first but write about it later so she can read it. I have also written stuff and then would bring it into a session but be able to say, "I wrote something that I need to share." I would then just tell her what was going on in my own words and then give her a copy of my journal entry.
