Prompt: I finally figured it out

"I wish I could say I finally figured it out," she thought to herself, rubbing excess facial moisturizer onto the backs of her hands so as not to waste a precious drop. She blinked, stared blankly at her reflection in the bevelled mirror, laced at the edges with black where the silvering had worn thin. She blinked again, then smiled then frowned, smiled again this time baring teeth that twinkled in the glare of the bathroom lights. She sighed and fluffed her hair. In the second before she turned off the light, the mirror caught the faintest glint of a tear in the outer corner of one eye. By the time she'd reached the bottom of the stairs, it was gone, the sparkle of her dazzling smile arming her for the day ahead.
