Notes.

Cynthia is a huge pushover. She'd kill herself for you if she made you feel disappointed. She would be glad to kill herself, actually. You see she is very depressed. She has multiple Heath issues that cause her to stand out, she has to see the counselor every day, and she is deathly afraid of interacting with a normal person.

But something unexpected happens. She finds a series of notes telling her to keep on living. She begins to become paranoid. Will she learn who wants to keep her alive? Or will she ignore the notes and keep going on with her pathetic life? Well of course not! What kind of story would that be?
