Yes, I journal and try to almost every day. Sometimes I journal about what is happening in my life, sometimes I write poetry, sometimes I write about dreams or what has happened in a session with my T. I have copied certain parts of my journal and given them to my T to read.

I journaled regularly before I started T, but it was mostly a chronicle of how terrible I felt. There wasn't a lot of insight. Now that I am in T, I make a point of writing down what we discussed in as much detail as I can. Then I usually write once or twice during the week--usually to reflect on what I discussed with T, and to make note of anything else that was important to me during the week. I review it before each session and it helps me remember what's going on with me emotionally.

At my T's suggestion, I began using art to express the feelings I had that words couldn't capture. Now I dabble in what some people call "art journaling" or "visual journaling," which combines art and journaling for a fuller picture of what's going on for me.

I started keeping a successful journal after going through Julia Cameron's book, The Artist's Way and using her "Morning Pages" technique: http://juliacameronlive.com/basic-tools/morning-pages/
