Too many people insist that to deal with emotional turmoil, you should entirely block out your negative memories and thoughts. However a 1997 research has clearly shown that the more you try to forget something, the more the brain dwells on it. Ironic, isn't it?
I recommend finding closure by writing poems and songs about your fears, confusion or anger. Researchers claim the act of writing about personal experiences has a cathartic effect because it inhibits parts of the brain linked to emotional turmoil, and increases activity in the region to do with self-control. Putting pen to paper is said to help the brain "regulate emotion" and reduces feelings of anxiety, fear and sadness.
The quality of the verse or prose written has no bearing on the effect on the author. In fact, scientists suggest that the less vivid and descriptive the piece, the better.
