Getting into fights with people makes my heart race. Not getting into fights with people makes my heart race. Even sleeping makes my heart race! I’m lying in bed when the thumping arrives, like a foreign invader. It’s a horrible dark mass, like the monolith in 2001, self-organized but completely unknowable, and it enters my body and releases adrenaline. Like a black hole, it sucks in any benign thoughts that might be scrolling across my brain and attaches visceral panic to them.
