I've noticed this pattern that I have, I can't really explain the why of it.
Days are for action or numbness, they are for making it or making progress.
Nights are for reflection, introspection, they are for feeling and learning.
It's weird to me that they don't like to mix much, my days revolve around doing things like meetings, Dr. appointments, pool therapy, massage, and chiropractic, picking up prescriptions, they also include numbness and shock and bravery, I try not to feel too much so that I can push through the day, feelings and emotions, and pain get in the way of the doing so I try to hold those for later.
Night is a different story it's were the pain collects dues it's when I become introspective and I reflect on what's happened, it's a time for sadness and loneliness, for self-doubts and revelations. Everything hurts, it feels impossible at night and also it feels most important at night. I can't shut down my thoughts at night.
I am the bravest in the day, I am most vulnerable at night. But I would not give up my nights raw and unfiltered for the mental numbness of the day.
