Thanks for Checking out my chord sheet :) I think this is all correct, sounded 
good for me! It's a great song, and really shows off Miley's vocal range! :)

Intro : Em

                     Am            C
So, its been like this from the start,
                  D                       Em
One piece after another to create my heart,
                 Am                  C
You mistake the game for being smart,
                        D                           Em
stand here, sell this, and hit your mark
                     Am
But the sound of the steel,
                      C
And the crush and the grind,
                           D                    Em
Itll scream cause who am I to decide my life?
                     Am
But in time it all dies,
                         C
Theres nothing left inside,
                           D             Am
Just rusted metal that was never even mine.

         C
I would scream,
          G                D
But Im just this hallow shell,
         Am
Waiting here,
          C
Begging please
            Em              D
God, set me free so I can feel

Hey!

Am
                C                 G
Stop trying to live my life for me,

I need to breathe,
     D              Am
Im not your robot
                      C                  G
Stop telling me Im part of this big machine
                    D
Im breaking free,

Cant you see?
         Am
I cant love,
          C
I cant speak,
         G            D            Am
Without somebody else operating me,
            C              G
You gave me eyes and now I see,
              D
Im not your robot,

Im just me.

Em
         Am
All this time,
                  C
Ive been misled,
                       D                      Em
There was nothing but cross-wires in my head,
                     Am                  C
Ive been taught to think about what I feel,
                    D                            Am
Doesnt matter at all until you say its real.
         C
I would scream,
          G               D
But Im just this hallow shell,
        Am
Waiting here,
          C
Begging please

Em                   D
