Invisible

Am I .......invisible?
Do you hear what I say?
Would you notice when I walk away?
Would you ask me to stay/

Or am I invisible,
and you don't know how I feel?
My idea's and thoughts,
you don't see them as real.

Am I invisible?
Do you see me here?
when I speak do you think about it,
or does it go out of the other ear?

I guess I am invisible.
Because you don't hear my cry.
So you can go about your day
and you won't have to hear me sigh.
