Monster.

i met a monster
she looked nice and friendly
we became friends
one time, we had a fight
she said i was ugly and worthless
i didn't believe her
but everytime she said it
how more she said it, how more i was going to believe it
i thought, as i accept it, we could be friends like before
but i was wrong
she was eating me up from inside
my mind was dead
i only had to kill my body
