cadaver

I was a cadaver.
You came, gave me a heart,
Made a human out of me.
I became alive, breathing,
Full of emotions.
But soon enough,
Just when I started
Enjoying your gift,
You inflicted in me
A pain like a thousand deaths.
Who would have thought
That a creator like you
Could become the same person
To destroy?
How come you took back
My heart
And changed me into a cadaver again?
