Capo on 2nd :) It's basically G5 , A5 , E5 , C5 for the whole song :) 

                  G5                      A5                     
Picture your heart breaking like a thousand times before
                E5                     C5
Picture your hands shaking you can't take it anymore
                G5                       A5
Picture your arms stretched out, trying to hold on
               E5                       C5
And then a hand reaches to save you from it all

G5                     A5
I've never been a fighter no
E5                       C5
I've always seemed to hold my own
G5                   A5                  E5                     C5
So I'm not gonna try to fight this feeling anymore
              G5                  A5
When the walls hit the ground
          E5                            C5
Build em up to watch them fall down 
          G5                  A5
You can take what is left
           E5                           C5
But the truth is that your love leaves me
G5                   A5                E5                 C5
Defenseless, defenseless, defenseless
             G5          A5                E5                 C5
Left me defenseless, defenseless, defenseless

Picture your heart mending, for the first time you feel whole
Picture your fears ending as you start to take control

I've never been a fighter no
I've always seemed to hold my own
So I'm not gonna try to fight this feeling anymore
When the walls hit the ground
Build em up to watch them fall down
You can take what is left
But the truth is that your love leaves me
Defenseless, defenseless, defenseless
Left me defenseless, defenseless, defenseless

And I will let down my guard
Just to know who you are
Defenseless, defenseless, defenseless

I've never been a fighter no
I've always seemed to hold my own
So I'm not gonna try to fight this feeling anymore

Defenseless, defenseless, defenseless
I am defenseless, defenseless, defenseless

When the walls hit the ground
Build em up to watch them fall down
You can take what is left
And forget about the rest
Cause I will let down my guard
Just to know who you are
Defenseless, defenseless, defenseless
