I'm not sure about the intro. But, the rest of the song goes likke this:

Capo 2(Chords according to capo)

Verse:

              C#m                A           E
I don't wanna be the girl who laughs the loudest
       C#m             A           E        B
Or the girl who never wants to be alone
              C#m              A                      E
I don't wanna be that call at 4 o'clock in the morning
             C#m                       A                     E    B
'Cos I'm the only one you know in the world that won't be home
C#m     A            E
A------h the sun is blinding
C#m   A               E
I----      stayed up again
C#m   A       E
O----h, I am finding
               C#m            A          E
That's not the way I want my story to end

Chorus:

C#m      A
I'm safe Up high
E                 B
Nothing can touch me
C#m                     A        E      B
But why do I feel this party's over?
C#m     A
No pain Inside
E                   B
You're like perfection
C#m                A      E     B
How do I feel this good sober?


And then the rest continues on with this pattern.
If you do not have a capo, then the equivelent of the chords are the following:

No capo

C#m = Ebm
A = B
E = F#
B = C#
