Invisible

Can you hear me?
Can you see me?
I'm walking now, do
  you care?
It's like I'm invisible,
  who cares?
I scream, do you
  hear me?
Can you see me?
Can you feel me?
I feel like I
  don't exist
I feel so alone
Nothing there, like a
  ghost in the air
I'm invisible to the
  world around me.
