I was once told (by an esteemed psychiatrist) that I have an engine ticking away inside me. My little red engine that chugs away continuously and unlike other people, it never turns off. It’s part of my Bipolar II diagnosis – I have no off switch. Instead, I have hyperarousal 24/7. But that’s a story for another day. Trust me when I say, I have an engine. I also have a battery.
