Billie Eilish - I try to live in black and white but I'm so blue

I try to live in black and white, but I'm so blue
I'd like to mean it when I say I'm over you
But that's still not true (Blue)
And I'm still so blue, oh

I thought we were the same
Birds of a feather, now I'm ashamed
I told you a lie, désolée, mon amour
I'm tryin' my best, don't know what's in store
Open up the door (Blue)
In the back of my mind, I'm still overseas
