There's a Monster Inside

There's a monster inside that will not die.
I cannot hide from it, cannot run from it, cannot kill it.
Can only let it swallow me whole.
Can only let it chew on my heart strings.
Can only let it feed on my happiness.
Can only let it suck out the life within me.
And for what purpose?
No matter how much it drinks it will never be alive like I was.

There's a monster inside that will not die.
A parasite that's growing, stretching it's talons out inside.
It fills my body, trying on my limbs for size.
It speaks through my mouth, trying out it's new voice.
It watches with my eyes, using it's new vision.
It uses my veins, pumping them with ink.
And for what purpose?
No matter how completely it takes over my body, it will never be alive like I was.
