I think it's an idea that my T would like me to use too, but I find it hard to email her and not send it. It's like I can't help but hit the "send" button without even proofing what I've written because I want my T to know what my feelings are, especially right after a session. I tried emailing and not sending once and it was very hard.
I may go back to journaling more because then there is no way to hit the "send" button!
