"Alex, honey, can you help me carry in the groceries?" His mother's voice, usually a source of comfort, now felt like a burden. He nodded, trying to lift himself from the couch. The muscles in his legs screamed in protest.

Outside, the sun felt harsh. He squinted, the brightness a physical assault. Each step felt like a battle against the earth’s gravity. The bags of groceries seemed to weigh a ton. He managed to shuffle into the house, placing the bags on the counter with a heavy thud.

Back in the living room, the couch looked like heaven. He collapsed onto it, the soft cushions offering instant solace. His mind was a blank canvas, devoid of thought. He closed his eyes, yearning for the peace of unconsciousness.
