Hi CassEve,
For me it's been writing. I kept a personal journal for a number of years. I found writing to be very effective both in providing a safe outlet for my feelings and because I could do that, writing it out often provided me with insight into my behavior and an ability to see overarching themes. It also served as a transitional object to remind me of my sense of connection or good feelings about my therapist when I could not "feel" them. I can be pretty left brained, so it's a way to bring both sides together.
I also write (bad
) poetry when I am having a very hard time expressing my feelings, especially when I started hitting the early, pre-verbal stuff. Art to me is where you go, when words can no longer express your feelings.
There was one poem I wrote about the relationship between love and pain that I sent to my T before a session, and we had a really deep talk about it. He made the connection from reading it that I carried a very deep belief that pain is an integral part of love and so he shared with me the understanding (which I very much agree with), that pain is a part of life, and love is the answer to pain. That shift was a very important one in my healing as it helped me see relationships as a source of comfort and strength rather than pain and hurt so that intimacy stopped being quite so frightening.
I have also written a blog about my therapy which has been helpful in a number of ways (if you're interested, the link is in my signature.)
My therapist has read my blog when I have asked, but I don't particularly receive guidance from him, nor have I feel the need of that. But I do bring a lot into sessions with me. So if I was able to gain some insight while journaling, I would usually address that at our next session.
Thank you for being open to hearing from clients, I think that is a highly desirable attribute in a therapist.
