She smiles at day, cries at night

Look at her, smilling and looking innocent,
butt deep down, the pain is like a hundred stabbing knives. She can't explain the pain you caused her as the knif touches her wrist. All she ever did was loving you, and u just pushed her down. she was too young to understand, and you were too foolish to noticed. Now as she is taking her life away, you are not there to stop her. Butt all you found left of her was a note left in her hand: I love him to death...
