I was halfway through my pre-calculus exam when the pain first made its presence known. It did not arrive as a gentle warning or a dull ache that I could easily set aside; instead, it felt like a sharp, white-hot needle pressing into the lower right side of my abdomen. The sensation was quick and terrifyingly precise, as if someone had reached beneath my skin to find a hidden bruise that had been waiting years to be disturbed.

At first, I relied on the only survival strategy I had ever known. I sat perfectly still and pretended that nothing was wrong. In the Gentry household, pain was never treated as useful information from the body. It was viewed as an inconvenient request, and making requests was a dangerous game to play.

A request for help invited deep sighs, theatrical eye-rolls, and lectures about being too sensitive. If the pain belonged to my younger half-sister, Chloe, the entire house would immediately shift its axis to accommodate her. When Chloe had a simple scratch, my mother dimmed every light, Rick drove to the nearest pharmacy, and the world spoke in hushed, reverent tones.

If I showed signs of a fever, my mother simply stood in the doorway with her arms tightly folded. She would ask if I was truly sick or if I was merely trying to avoid my responsibilities for the day. By the time I turned eighteen, I had mastered the unspoken rules of the house. I knew I had to need less, want less, and find a way to hurt without making a sound.

So, as the ache intensified, I lowered my gaze back to the worksheet on my desk and forced my pen to keep moving across the page. Mr. Garrison was standing at the whiteboard, explaining complex equations to a room full of seniors who had long since stopped pretending to care. It was a cold December morning in Shelbyville, Tennessee, and the classroom radiators were clanking loudly while filling the room with a dry, metallic heat.

A few students had their heads resting on their arms, and I could hear the rhythmic tapping of a pen against a notebook somewhere behind me. Outside the window, the sky was a flat, heavy gray that promised a thick layer of snow by the time school let out for the day. I looked down at the math problem in front of me, which consisted of two fractions and several variables.
