This is the acoustic version from Lydia's new Acoustics EP; I know this isn't 100% 
correct but it sounds pretty close. 
Only strum each chord once for the chorus.

F             C            Em
A Smile on my face again
           Am
'Cause I'm laying with her skin
F  C                G
I  will be here all night
You'd best get your words right
F                   C            Em
'Cause I've tangled them before
              Am
She caught me running out the back door
F     C                G
Never will it happen again
Yea I found out I've been

F                   C                  Em
I've been out of my mind for some time now
Am                 F
   But come on you knew that
C                             G
   You know where my head has been at
But you're still hoping it comes back 

F            C             Em
I thought of words to say
            Am    
I wrote 'em down for her sake
F     C                 G
Never did she ever complain
Yea she's seen my worst day
F                C             Em
'Cause we've got so much to do
           Am
The lights poured through your bedroom
F   C                  G
Never will I leave here again?
Yea I found out I've been

F                   C              Em
I've been out of my mind for some time now
Am                 F
   But come on you knew that
C                             G
   You know where my head has been at
F                   C             Em
I've been out of my mind for some time now
Am                 F
   But come on you knew that
C                             G
   You know where my head has been at
But you're still hoping it comes back
