The world felt muted. Amelia sat on the park bench, the vibrant colors of autumn, normally a source of joy, now just a dull wash of hues. Her fingers traced the worn wood, the cold seeping into her skin. The doctor had given her the news this morning, the same sentence that had echoed in her head all day. The same rare condition.

She watched children laugh as they chased pigeons, their shrieks of delight grating on her ears. It had become increasingly difficult to find joy in things. Her appetite had vanished, and she pushed the food around on her plate. Even the simplest tasks, like getting out of bed, felt like an insurmountable challenge. The world’s light felt too bright, its noises too loud.

A man approached, his posture slumped. He sat heavily on the bench, not glancing at her. Then he let out a choked sound, a sort of sigh of despondency. "This weather," he muttered, his voice gravelly. "It just gets worse and worse, doesn't it?" Amelia nodded slowly, her heart skipping a beat. It was the same unspoken acknowledgment, the same weary acceptance she knew too well.
