Capo 4 (the song is in the key of F# but I would rather use the capo on 4 to get the same key.  
You can put the capo on 1 and transpose the chords to the Key of F if you so choose)

Intro: D  G  A  D 

A        D          G                 D
You're having second thoughts, I can tell by the way you look at me 
           A     G                 D   A
I can tell by what I see you no longer believe in me 
       D       G                      D
I'm havin' bad dreams, can't seem to get back to where we used to be 
D                        A    G      A          D
Sometimes it feels like we're worlds apart, I've got too much on my heart 
 
Refrão -------------
             G    C G                        D
I've got too much on my heart     and I don't like to feel the pain 
                A  G                  A
And I don't know where to start to make you love me once again 
                    G      A                D          D/C#   Bm
I don't have time to make you understand, Lord this thing is gettin' out of hand 
Bm                  G  A                    D
Pain shoots through me like a dart and I've got too much on my heart
--------------------
 
Don't be so cold to me I know you've changed but it's still hard for me 
It's too late I realize I can see it in your distant eyes 
You needed all of me but I can't be there like I used to be 
And Lord it's tearin' me apart, 'Cause I got too much on my heart 
 
Chorus
