I am...

I am described as a failure
I'm like cancer which can be hard to cure,
You could call me a waste of time,
And being like a penny you are hard to find.

I'm like a dark shadow,
not noticed,and without light i will not show,
I'm a piece of string,
tied up,and not capable of anything.

I'm the pavement,you walk all over me,
fuked up and used constantly,
I'm the person you never considered,
lonely with a life that\'s withered

I'm the next evil thing,
that is hated by everyone, just ring,
and i will make you\'re entire life a sin,
that is making the world seem thin.

you will follow me down to hell,
and capture this evil spell
for i am just a messenger,
that no one could ever tell.
