How Sad

My grandson sent this to me (his little sister is 3 so it hit him in his heart). There was encouragement to pass it on. I'm not sure how that will help children in this situation but here it is.

My name is Sarah, I am but three,
My eyes are swollen, I cannot see
I must be stupid, I must be bad,
What else could have made my daddy so mad?
I wish I were better, I wish I weren't ugly,
Then maybe my Mommy would still want to hug me .
I can't speak at all, I can't do a wrong
Or else I'm locked up all the day long.
When I awake I'm all alone.
The house is dark, my folks aren't home.
When my Mommy does come I'll try and be nice,
So maybe I'll get just one whipping tonight.
Don't make a sound! I just heard a car
My daddy is back from Charlie's Bar.
I hear him curse, my name he calls
I press myself against the wall.
I try and hide from his evil eyes
I'm so afraid now I'm starting to cry.
He finds me weeping. He shouts ugly words,
He says its my fault that he suffers at work.
He slaps me and hits me and yells at me more,
I finally get free and I run for the door.
He's already locked it and I start to bawl.
He takes me and throws me against the hard wall
I fall to the floor with my bones nearly broken
And my daddy continues with more bad words spoken.
"I'm sorry!" I scream, but its now much too late
His face has been twisted into unimaginable hate.
The hurt and the pain, again and again
Oh please God, have mercy! Oh please let it end!
And he finally stops and heads for the door,
While I lay there motionless sprawled on the floor.
My name is Sarah and I am but three,
Tonight my daddy murdered me.
