Regret Lyrics

I still walk and I still breathe,
I'm not the man that I could be.
There was a hole here in my chest,
Now it's filled up with these regrets.

Is the ending written down
Before we even read the play?
And is the ending hidden there
Until we turn the final page?

If I'd learned my lesson sooner,
If I'd sorted out my head
Then I would still be with you,
And I would not have one regret...
I would not have one regret...
