Is There a Purpose?

I feel so alone
As watch people go by they stare right through me.
I don't exist.
Why?

Why Do I Exist?
Do I have a purpose?
Is there even a purpose to this cruel world?
Why?

Does anybody have a purpose?
Are we just here for nothing?
Are we just pawns in a game?
Why?

I just want to know?
Why do we exist?
Are we even real?
