I don't blame you

Last night I lay on my bed and cut my arm
No, its not sick, its not disgusting, its self harm
And I really don't think you'll ever understand,
You blame yourself and the way you raised your hand
But you hitting me when I was a kid
doesn't really explain the things I did
and it doesn't give explination to the deep dark hurt inside
and it doesn't give me reasons why I lie awake and cry
can't you see I don't blame you?
its noones fault and thats the truth
self harm, or cutting its just something I do
Its my way of coping, and its nothing new
