My T gave me Every Day Gets a Little Closer by Yalom to borrow. It's about a client that writes about her sessions: everything she didn't say, everything going on underneath the surface, her impressions of what her T said, etc. The T in the book does the same, and they share the letters six months later.

I think my T wants to do a similar thing on a smaller scale with me because she knows how much I like to write. I'm really excited. Anyway, I recommend the book- it's interesting so far!
