It’s called “cognitive offloading.”
When you write something down, you’re using a piece of paper to store information, which would otherwise be held onto by the brain.
If it’s stored somewhere else (or in someone else’s brain when you tell them about it), you don’t have to remember the actual information anymore. You just have to remember where it’s stored.
Frustration and anxiety are emotions, and emotions are global (brain-wide) evaluations of our level of aliveness.
Negative emotions indicate a decrease in our aliveness (or potential aliveness), and positive emotions indicate an increase.
Emotions themselves only last 90 seconds or so.
What keeps them circulating and replaying is the story we tell ourselves about them. The story triggers the emotions, and the emotions trigger the story.
When you offload the story, the emotion can fade more easily because your brain is not holding on as deeply to all the information related to the emotion.
