You've got on your sports bra, your dark-rimmed teacher glasses, your hair in a ponytail. “You're a fucking badass,” you tell yourself, as the pain hits you again. The funny thing about acute pain is that it always takes you by surprise, no matter how many times and how often you've experienced the exact same thing. “You just have to get to the sink,” you tell yourself. Attempting to do anything while in pain is a challenging exercise in multi-tasking. But you make it, you always make it. You look in the mirror for reassurance. The pain, again, in waves.
