I need a theme song for my story..help?

here is the link to my story
http://stories.mibba.com/read/396304/Why-cant-we-all-feel-like-gifts-from-God/

I need a song that fits the description of this song. if you can't
access the story here is the description of it.

This a diary of a wishful "fat" girl. She's tired hard to become
skinny. Her diary is full of wishes and her anger with God. She
doesn't believe that she is a gift from God like her mother has always
been telling her. She feels fat and she can't find an escape so she
clings to her diary.

Thanks.
