Knot

It's midnight, I want to wake up at five, I'm working at eight. My brain can't just relax and stop overthinking, trying to find reasoning behind other people's actions. My dead-philosopher emperor would be so ashamed of me tonight. How do I get rid of this knot in my thinking? I know how to, really, but I'm so weak in character right now. I'll try to sleep and I'll wake up strong as steel. I promise.
