This comic panel is scarily accurate when it comes to my own thought patterns – I have quite often “overdosed” on my own mind and occasionally still do. It’s gotten a lot better, but there are days when I have to forcefully tear my thoughts away from difficult situations or I’ll end up seeing my impending failure before I even left the house in the morning.

I like this … I get so stuck in my thoughts sometimes, almost to the point of being overwhelmed. When I was a truck driver, I had way too much time by myself, especially on the long days when I wasn’t forced to talk to anyone.
Too many hours of uninterrupted solitariness get me there too – disconnected from the world around me, pre-occupied with the microcosm of my thoughts. Sometimes I don’t even notice until something catapults me out of that state…
