Rain lashed against the windows of Maya's apartment, mirroring the turmoil in her chest. She stared at the email, the words blurring through unshed tears. *You have a half-sister.* The news, delivered so clinically, felt like a physical blow. Her fingers traced the screen, re-reading the details: a woman named Clara, living in a different state, the product of a brief, long-ago affair. Maya felt a hollowness spread through her, a vast, empty space where she thought her life had been. She wrapped her arms around herself, a futile attempt to find some measure of comfort.

The silence of the apartment pressed in on her. She hadn't left the house all day, barely moving from the worn armchair. The remnants of a forgotten cup of coffee sat cold on the table, a testament to her lack of appetite. Her phone lay silent on the table, the messages piling up, unanswered. She was usually so responsive, so eager to connect, but the world seemed distant now, a muffled roar she couldn't quite bring herself to join.

A wave of exhaustion washed over her. She got up, slowly, and moved towards the bedroom, her footsteps heavy, each movement feeling like an unbearable effort.
