Dido - My Life chords

All the other versions here don't sound quite right, so I tried to figure out the 
right chords. This is the album version.

Capo 3rd fret
Intro: Em B C B7

         Em       B       C              B7             Em B C B7
What I choose to do is of no concern to you and your friends
         Em     B           C     B7       Em         B       C  B7
Where I lay my hat may not be my home, but I will last on my own

            Em           B            C             B7 Em
'Cause it's me, and my life, it's my life, it's my life

         Em       B          C          B7             Em     B C B7
Oh the world has sat in the palm of my hand not that you'd see
         Em         B         C         B7      Em          B              C B7
And I'm tired and bored of waiting for you and all those things you never do
            Em           B            C             B7 Em
'Cause it's me, and my life, it's my life, it's my life
