I'm not quite sure about the lyrics, but comment for changes ;) 

Intro G D Bm G x2

               Bm     G          D
What was this great idea I had planned
               Bm          G                    D
Hanging by a thread is my heart see it in your hand
         F#            G                    D
Hold it next time we speak it could be the last
         F#            G         D
For the last time we spoke I forgot myself
     F#                       G
I remembered too late that I lost myself
        G           G
But I found, Is a power
         Bm          F#
That is greater than I
      Bm           G
It’s greater than you and I
      D             A           Bm         G
It’s more than the sum of what love was between us
      D            F#m        Bm           G         D
We’ll go there together or strangers I’ll always be with you

                      
               Bm          G                   D
Tell me your stories I’ll learn not to fall behind
                       Bm           G                 D             
‘cause life is but a journey or a heart beating over time
          F#          G                      D
Don’t be hard on yourself give the truth a chance
              F#         G             D
And give yourself to surrender, don’t lose yourself
         F#                       G
Don’t forget who you are behind someone else
            G              G 
‘Cause you know there’s a power 
          Bm         F#
That is greater than I
     Bm            G
It’s greater than you and I
      D             A           Bm        G
It’s more than the sum of what love was between us
      D           F#m        Bm            G          D
We’ll go there together or strangers I’ll always be with you

 Bm             A           G
Don’t lose yourself out at sea
        Bm            A                   G
‘Cause fear is just faith you just can’t see
       F#m        G
And I believe in you
      F#m         G
And I believe in me
       A          G      
And I believe in something 
             
         Bm          F#  
That is greater than I
       Bm          G
It’s greater than you and I
      D             A           Bm         G
It’s more than the sum of what love was between us
      D          F#m         Bm             G        D
We’ll go there together or strangers I’ll always be with you
