I can't play the strumming pattern that Carrie uses so instead I pick
the notes like this, it is just my alternative: 

*3/0 means you can play on three or open*

 G*               C                Am               D
e|--------3-------|------0---------|-------0--------|-------2--------|
b|----3/0---3/0---|----1----1------|-----1---1------|----3----3------|
g|--0------------0|--0--------0----|---2-------2----|--2---------2---|
D|----------------|----------------|----------------|0---------------|
A|----------------|3---------------|0---------------|----------------|
E|3---------------|----------------|----------------|----------------|

Carrie uses standard tuning with a capo on second fret, so do I.

            G              C
I'd hold my breath but you took that away, 
         G          C
if you'd ask me i'd pretend i'm ok 
        G        C
coz i'd wait forever and a day 
       Am                 D
but it ain't that easy to make you believe (in) me 

   G            C
so i'll pour my heart into words
         G          C 
and i'll write them down in a verse 
      G              C
coz i can't think of anything worse 
     Am                 D
than finding it easy to make you believe (in) me 

               G
Tell me you'll fight,
             C 
tell me that you won't let go 
       Am                       D
when I need you the most in the night 
            G
Tell me i'm right
        C 
Tell me you want me to stay 
        Am                   D
tell me you're not afraid to hold me tight 
                          G
Tell me that you're gonna fight 

           G         C
If i'm the last girl left on this Earth 
          G           C
would you hold me and tell me i'm worth
     G                C 
everything and sing a song unrehearsed 
        Am                      D
coz i'm feeling uneasy that you won't believe (in) me

               G
Tell me you'll fight,
             C 
tell me that you won't let go 
       Am                       D
when I need you the most in the night 
            G
Tell me i'm right 
            C
Tell me you want me to stay 
        Am                   D>>>
tell me you're not afraid to hold me tight                
>>>D
Tell me, 

             Am
tell me that i'm not crazy 
   C
to think you could love me, 
  G
I think you could love me 
  D
I think you could love me

               G
Tell me you'll fight,
             C
tell me that you won't let go 
       Am                       D
when I need you the most in the night

               G
Tell me you'll fight,
             C
tell me that you won't let go 
       Am                       D
when I need you the most in the night
            G
Tell me i'm right 
            C
Tell me you want me to stay 
        Am                   D
tell me you're not afraid to hold me tight 

                          G
Tell me that you're gonna fight
C                         G
Tell me that you're gonna fight
C                         G**
Tell me that you're gonna fight

** for the last note either strum it or you could play the b,g and thick E strings 
at the same time.
