You've already killed me

I am invincible
nothing can hurt me.
I'm already dead
just in a living body.
you've already killed me
I'm already gone.
your tears mean nothing
you've been killing me all along.
don't worry at all,
i suffered great pain.
you got what you wanted
and you'll get it again.
but not from me
because I'm already dead
you murdered me easily
with those words you said.
i believed you were there for me
and I'll admit that was my fault.
I'll admit to being stupid
when i thought you'd catch my fall.
so maybe it wasn't murder
maybe i caused my own death.
you were just in the passenger's seat
telling me where to wreck.
so congratulations
for a job well done.
you committed the perfect crime
I'll admit i lost and you won
so why are you still here?
you've already killed me.
why are you still trying?
why is your knife still stabbing?
you know it doesn't hurt me.
you can't cause me anymore pain.
so why are you still coming around?
why are you back again?
i know your tricks now
your sweet words mean nothing to me.
you're never gonna get me back
can't you see?
it's over, you've won.
get out, move on, it's not fair.
you've done all of this to me
and you expect me to still care?
well get over it
because there's nothing left to do.
someone has killed my ability to care
and the murderer was you.
