I agree that whatever works for you and your t is good. My t encourages me to e-mail between sessions, especially if there's something we're working intensely with. She recognizes that not everything happens in that one hour a week and that for me, it's really helpful to have support and feedback between times. It's also a way of strengthening our connection and building trust, for me at least. We usually talk about the content of the e-mails during sessions, however. I also use them to bring up things that I want to bring up in session but are afraid of hiding. In that case, she'll bring them up right away to see where we want to take them. For me, it makes talking face to face easier, but I know that for some people it becomes a way to hide.
