Teach me Show me Hurt me Leave me

Teach me how to die with out any pain.
Teach me how to scream ever so silently.
Teach me how to have a stone cold heart..
Just like you...
So I can block out my feelings and never cry.
Ignore my every move do I can die.
Be cruel,be mean I've suffered worse.
No you will not hurt me anymore.
My heart will be a rock.
Unmoving,uncaring never to be hurt.
I thought I really loved you.
But looked where thats got me.
You left me all alone....by myself.
You didn't even care.
You just left.
What exactly did I do wrong to not even get a goodbye?
What did I do wrong..
Why did you leave...
