Without her i'd be dead

She really scared me tonight
everything went from black to white
she looked so happy then came a tear
saying she doesn't deserve to be here
thats what she doesn't understand though
but i will find a way to let her know
that without her i would have no life
my only true friend would be my knife
she is the only one who knows me
she makes my world a better place to be
she has always listened to what i said
without her i would be dead
