Well, I don't know if it's a "thing"; I just made it up. But I've done exactly that a few times in my life when I was REALLY torn, stuck, frustrated. I just said, "FUCK IT!" and started writing. Writing writing writing. List after list after list. So many details. It got all that shit out of my head and onto paper, especially the answers to the question, "What am I avoiding right now?" and the more painful it was to even THINK of "the thing", the more I knew I was close to the very thing I needed to address and face. After it was done, I forgot about them and got on with life. But it was very useful.
