I did some narrative work with my T, mostly for trauma processing. In my case, I wrote about some of the bad memories--and then also wrote about some good(ish) memories from the same period, some normal things. It really did help me see that my life was bigger than the bad things that happened to me. That I was more than what happened to me.

It took a bit for me to stop being self-conscious about my writing. T had to explain he was reading and helping me with the content of it, so the quality wasn't the important part.
