I am Unknown (dark ending)

I am unknown
you cannot see me
unless you really try

When we are near
you still feel alone
as if I'm your shadow

I only wish you would see me
when you need someone
when your feeling sad

your crying on your bed
near a bloody sink
and a rope near your head

I scream for you
but you do not hear
because you do not look for me
