First Tab! Yay! Sorry if it's not perfect D=

Capo on 2nd :) It's basically G,Am, Em, C for the whole song :) 

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

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