"Teen Diary Exposed!" The headline screamed at her from her phone. Chloe felt a sudden, inexplicable flush of heat. This was a nightmare. She dropped the phone on the bed, burying her face in her hands. The room felt stifling, the air thick with unspoken anxieties.

She picked it up again, knowing she had to look. The website was garish, the design a painful reminder of questionable fashion choices. She scrolled, her eyes darting from word to word. Each entry was a punch to the gut. The hurt she'd felt at those moments was again palpable.

She slowly began to read through the entries. Her lips began to tremble, and a single tear escaped. The world, for a moment, felt very, very small. The girl she was, she was almost unrecognizable.
