Invisible

You've told me all,
You've said your words,
How he never calls:
How you're never heard.

And he doesn't care,
And you've told me so.
And why do you stay?
You've never known.

And I help you down,
And you cry for me,
And yet every round,
It's back up the tree.

Seems you don't care,
Or that you don't see,
What you mean to him,
And what you mean to me.

And I'm still alone,
And I don't know why,
And I can only ask:
God, why am I

Invisible?
