My arms stings and the blood is just running down the side
and everyone thinks I'm perfectly fine
I hide it so well everyday
If i even tried to tell someone i couldnt even imagine what they'de say
You see I'm the girl with the big smile
and who can make you laugh a while
everyone thinks they know who I am
or either just don't give a damn
they see me as the happy girl
living in some kind of perfect world
but if they only knew how I cry myself to sleep
or about the scars under sleeves I keep...
