Misery with a Delicate Voice

I'm inside your head;
& I won't leave 'till you're dead.

I crossed my heart;
that you'd be a discard.

I'm inside your head;
& I won't leave 'till you're dead.

I stuck the needle in my eye;
so I wouldn't watch you cry.

I'm inside your head;
& I won't leave 'till you're dead.

I hoped you would die;
because of the beautiful lie.

I'm inside your head;
& I won't leave 'till you're dead.

I watched as you fell to the ground;
not making a single sound.
