Rain lashed against the window, mirroring the storm brewing inside her. The grayness of the world seemed to seep into her bones. Ava sat by the window, watching the droplets race down the glass, each one a tiny, fleeting moment of existence. She’d lost interest in her courses.

Her journal lay on her bed, open to a page filled with messy, tear-stained writing. The air was thick with the scent of lavender from the diffuser, a futile attempt at creating calm. Her roommate, Sam, returned from class, a nonchalant expression on his face. Ava looked away, a bitter taste rising in her throat.
