Who Am I Poem by sandy nobody

im the lowest person on earth
i shouldve died at birth

im meanest of the meanest
staying away from me is best

i can and will ruin your life
cut you like a knife

i am your nightmare
even when im not there

my words will taunt you
your dreams, i will haunt you

i will chew you up, spit you out
i will walk away as you shout

im not very nice
my heart is cold as ice

i will get to you deep inside
from me, you cannot hide

i will torment you
and theres nothing you can do

who am i

i

am
