Verse 1:
Abm                                  E
 I don't think I've slept in a month
                                   Abm
I don't wanna dream, it's too much
                           E
Playin' in my head like a picture
Abm                                   E
 Haven't seen myself 'cause she's gone
                                       Abm
Crying used to help, now it feels wrong
                                    E
I'm drowning here alone, yeah, go figure

Pre-Chorus:
         Gb                      Abm
'Cause I finally thought that I found you
             E
But you were wasting my time
    Gb                 Abm             E
I'm over you, dying without you, it's fine
-nc-
But

Chorus:
B              Gb                            E
 Every time you look at her, I close my eyes
E                               E                      B
Does she keep you up all night, keep you up all night?
                Gb                                E
Why'd you say "forever" if you changed your mind?
E                               E
You still keep me up all night, keep me up all night

Verse 2:
Abm                                E
 You blow me off like I'm a mistake
                                     Abm
Show her off, oh god, I can't take it
                                E
Why'd shе had to look like a model?
       Abm
No, it didn't take you long to forgеt about me
        E                                              Abm
Tell me how you're moving on, baby, I still can't sleep
                             E
How the hell you look so unbothered?

Pre-Chorus:
         Gb                      Abm
'Cause I finally thought that I found you
             E
But you were wasting my time
    Gb                 Abm          E
I'm over you, dying without you, tonight

Chorus:
B              Gb                           E
 Every time you look at her, I close my eyes
E                               E                      B
Does she keep you up all night, keep you up all night?
                Gb                                E
Why'd you say "forever" if you changed your mind?
E                               E
You still keep me up all night, keep me up all night

Bridge:
Gb                        Abm
 I miss the way that we were
                        E
And I'm no better than her
E
I know you better than her, oh
Gb                           Abm
 You know that I was here first
                        E
And I'm no better than her
              E
I know you better than her


      B                   Gb
'Cause your voice was the soundtrack of my summer
            E
Do you know you're unlike any other?
-nc-
You keep me up all night

Chorus:
B               Gb                           E
 Every time you look at her, I close my eyes
E                               E                      B
Does she keep you up all night, keep you up all night?
                Gb                                E
Why'd you say "forever" if you changed your mind?

You still keep me up all night, keep me up all night

You still keep me up all night, keep me up all night

     Yeah, wasting my time
E                               E
You still keep me up all night, keep me up all night
