My Panic Attack Solution

I’m writing an essay for my Honors English, over the summer homework. We had to read a book of our choice, and find a song that fits the theme of the book. The novel i picked was "Get Well Soon" by Julie Halpern. Its about a teenage girls parents betray her and put her in a mental home, because of her panic attacks, but really theres NOTHING wrong with her! But she actually makes new friends and a boyfriend while shes in there, and when she gets out, shes stronger, and she doesn’t cry all the time and such. These lyrics,

Do you know what they say,
Do you know what they say, what they say about you?
Do you know what they do?
Do you know what they do, when you leave the room?

Never thought twice about holding your tongue,
Once upon a time you were so young.
Everywhere you carried around your soul.
In the night they stole it, left you skin and bones – knife in your back.
Laughing aloud at your expense, fed themselves on innocence – knife in your back.
Their attacks inserted doubt, now you’re stranded in the cold with a knife in your back.

Do you know what they feel?
Do you know what they feel, what they feel for you?
Do you know how they play?
Do you know how they play, how they play inside you?
Do you know what they steal?
Do you know what they steal, what they steal from you?
Do you know how they prey?
Do you know how they prey, how they prey upon you?

Never thought twice about holding your tongue,
Once upon a time we were so young.
Everywhere you carried around your soul.
In the night they stole it, left you skin and bones – knife in your back.
Laughing aloud at your expense, fed themselves on innocence – knife in your back.
Their attacks inserted doubt, now your stranded in the cold with a knife in your back.
Tell me did you grow after all these years?
Giving up control and buying into fear,
Night slips into morning and days remain unchanged,
But their mighty appetites will not be tamed.

Do you care, do you care?
Do you care what they say?
Do you care what they say, what they say about you?
Do you care how they prey?
Do you care how they prey, how they prey upon you. Upon you.

Do you think, with these lyrics the whole "With a knife in your back" can compare to the way her parents betrayed her? Unless you have a better song. Help? Thank you,

This song seems highly appropriate…good job in finding it.

Who sings it?
