am i in a book?

Amaya is a small-town girl who now lives in a big but quiet city. She is 27 now. She "has" 2 friends. She opened a random package at her door and she is now cursed and she doesn't know it yet but her soul got stolen. She thinks she is being watched by a demon so she later calls an exorcist. But the demon hides in Amaya. When the demon is still there months later, she calls back the exorcist and tells him " Do a clean up of my place and me." But the demon hears this because the demon has her soul so he hides in the candy bar from the packedge. The exorcist also brings a normal cleaner he takes the candy bar because it expired on 7/29/1669. But a year later another packedge comes. And she has now learned so she doesn't open it but gives it back to where it came from. But since the address is scathed out she can't give it back so she just decides to bring it back to her house...
She ends up being cursed again but since she is used to it now she deals with it but once the demon saw she didn't care he brought more demons.
she finally goes so crazy she eats the candy bar and realizes she is in a book so for 2 months she goes crazy telling the reader to get her out of there till she finally fades away while jumping out her 9-story window.
