Lyrics:

All that you see out in front of you
Is how you feel inside your head

And that is what we call anxiety

And then you think
Can I observe the thinker
Thinking the thoughts?
So I am worried
And I ought not to worry
But because I can't stop worrying
I'm worried because I worry
And you see where that could lead to
That is what we call anxiety

No amount of anxiety makes any difference
To anything that's gonna happen
