《What Have I Done》的歌詞如下：
歌曲原句：
Verse 1：
I'm sorry, I'm sorry
I didn't mean to hurt you
You said you wanted space
And I gave you more than that
Chorus：
What have I done?
To break your heart in two
All the pain, I caused you
Can't take back what I've done
Verse 2：
I don't know what came over me
It was a selfish act of love
Now I'm feeling all the pain
That I caused you, and it's all my fault
Chorus：
What have I done?
To break your heart in two
All the pain, I caused you
Can't take back what I've done
Bridge：
I apologize again
For what I've done to you
I know it was wrong to do so
But please give me another chance
Chorus：
What have I done?
To break your heart in two
All the pain, I caused you
But now I'm asking for you
(repeat bridge)
Chorus and end：
Can't take back what I've done
But I will make it up to you
Sorry, I'm sorry, again and again.
