If only death came to my 'love'

You used to be my cure,
Yet now you're my weakness,
You used to be my everything,
Yet now you're my nothing,
Perhaps Ive lost everything,
So nothing can make me sad,
All of my friends are bad,
And i shall never be glad,
Only knowing that you're alive and walking,
Is enough for me to start coughing,
Ill slit my throat if it'll kill you,
But it wont cause you're a heartless b@$tard.
