It feels like there is a jukebox in my brain that automatically plays all kinds of songs. Different eras, genres, etc. I'm used to it by now since its been going for years. I am always thinking about something, usually a few things. And I am not purposely thinking about things, if that makes sense.

I think that is the root cause of my insomnia. My body gets tired but my brain is too busy to sleep. The only time this is not the case is when I am deeply depressed. I feel flatlined. I shudder thinking about it.
