[Verse 1]
What if it kills me?
What if living life without you in it is more than I can bear?
What if I'm lonely?
What if having half of someone's heart is better than nobody there?

[Pre-Chorus]
What if I know that you're bad for me
And there's no way we're right?
But what if I still wish you were holding me at night?
What if I know not being with you is better for my health
But I get jealous when you're with someone else?
Oh, but what if I don't?
Yeah, what if I don't?

[Chorus]
What if I don't remember to miss you?
What if you never cross my mind?
What if I'm stronger than you let me?
Believe me, I'm sleeping just fine
It's hard to imagine I won't
See you laying on my pillow
When I close my eyes at night, and I'm alone
But what if I don't?
But what if I don't?
[Verse 2]
What if I see you
Holding hands with another girl?
Will I wish that that could still be me?

[Pre-Chorus]
What if I know that you're bad for me
And there's no way we're right?
But what if I still wish you were holding me at night?
What if I know not being with you
Is better for my health
But I get jealous when you're with someone else
Oh, but what if I don't?
Yeah, what if I don't?

[Chorus]
What if I don't remember to miss you?
What if you never cross my mind?
What if I'm stronger than you let me?
Believe me, I'm sleeping just fine
It's hard to imagine I won't
See you laying on my pillow
When I close my eyes at night, and I'm alone
But what if I don't?
But what if I don't?
[Refrain]
What if it kills me?
What if living life without you in it
Is more than I can bear?
What if I'm lonely?
What if having half of someone's heart
Is better than nobody there?

[Chorus]
What if I don't remember to miss you?
What if you never cross my mind?
What if I'm stronger than you let me?
Believe me, I'm sleeping just fine
It's hard to imagine I won't
See you laying on my pillow
When I close my eyes at night, and I'm alone
But what if I don't?
