The most horrific thought ever imaginable. She fears it will happen to her. Death.
All she would have to do is stumble into someone's trap. Or maybe fall asleep, never to wake again. She could get a sudden illness. A slow, painful, torturous death is what she fears most.
Even the thought of losing someone she loves sends her into shock. Her family, friends, and classmates. There could be a car accident. She would not know.
Anything. Anything that even looks or sounds painful makes her want to hide. Hide in that bundle of pillows and blankets that is always there to comfort her.
