I keep a therapy journal but it was my idea. I write down everything that is said during my sessions (I record them also) and I use the notes to further reflect on the session and to refer to when I am having a hard time or need to remember something. I think its one if the best things I have done to really maximize my therapy. My T thinks its a good idea. She doesn't make me show her anything I don't want to. I might end up showing her someday.
