Just Confused

I woke up this morning with a thought in my head
"Am I thinking clearly?" is what I said
Then I started wondering if that was true
But I'm not quite certain what to do

I'm not sure, no I'm not sure
(Not sure at all!)
I'm not sure if I'm not sure anymore
(What's the score?)
Could I be certain of uncertainty?
Or am I just confused about being confused, you see?

Sometimes I think that I know what I know
But then I doubt if that's the way to go
Maybe I'm wrong about being right
Or right about being wrong tonight

Not sure, not sure, not sure at all
(Round and round in circles!)
Not sure if I should stand or if I should fall
(Up or down!)

Ich bin meshuge, dos iz klor
Tsu zayn oder nit tsu zayn, ich hob moyre
Efsher yo, efsher neyn
Ver veys vos ich meyn?

What if everything I doubt is true?
What if nothing that I think I knew?
Am I here or am I there?
Should I sit or should I stand?
Do I even understand
What it means to understand?
HELP!

Now let me break it down and analyze my mental state
Am I early, am I late? Can't seem to concentrate
Got a PhD in doubt, that's what I'm all about
But wait - can I be sure that's what I'm thinking 'bout?
My therapist says "trust yourself" but I just can't decide
If that advice is right or if I should run and hide
Layer upon layer of questions in my brain
Making me go crazy, driving me insane!

I'm not sure, no I'm not sure
(Not sure at all!)
I'm not sure if I'm not sure anymore
(What's the score?)
Could I be certain of uncertainty?
Or am I just confused about being confused, you see?

After all this thinking, here's what I conclude:
I might be confident about my uncertain mood
But don't quote me on that, I could be wrong
That's why I'm singing this confused little song

I'm not sure... I'm not sure... I'm not sure...
(Or am I?)
