Worthless Depression

Am I just a shadow
like a cloud in the sky
why am I like this
please God tell me why

Is my life worthless
filled with nothing but pain
am I a shadow of black
like a cloud filled with rain

When something bad happens
I don't cry, I freeze
like the wind to the sea
like a cold winters breeze

Am I here for a reason
does my life have a purpose
or am I just a human
feeling lonely and worthless
