[Intro]
Oh, oh, oh, oh, oh oh-oh-oh
Oh, oh, oh, oh, oh oh-oh
Oh, oh, oh, oh, oh oh-oh-oh
Oh, oh, oh, oh, oh oh-oh

[Verse 1]
I'm waking up, my body aches
The pain is back, my mind's awake
What happened here? Can't recollect
Who left sincere marks on my neck?
A night so young, I couldn't see
That you were here, in front of me
I do not care, you don't exist
I'm leaving now, you won't be missed

[Chorus]
Think to yourself, "What have I done?"
I'll live to see what you'll become
A heart that's blacker than your lungs
You can't undo what has been done

[Verse 2]
I cannot sleep, a restless night
I'm worried now, are you alright?
What's going on? I do not know
Your other form will truly show
And so it seems, you only care
For alcohol and poisoned air
I cared too much, my heart is real
You're leaving now, I'll slowly heal
[Chorus]
Think to yourself, "What have I done?"
I'll live to see what you'll become
A heart that's blacker than your lungs
You can't undo what has been done

[Bridge]
Oh, oh, oh, oh, oh oh-oh-oh
Oh, oh, oh, oh, oh oh-oh
Oh, oh, oh, oh, oh oh-oh-oh
Oh, oh, oh, oh, oh oh-oh

[Chorus]
Think to yourself, "What have I done?"
I'll live to see what you'll become
A heart that's blacker than your lungs
You can't undo what has been done
Think to yourself, "What have I done?"
I'll live to see what you'll become
A heart that's blacker than your lungs
You can't undo what has been done
