The song follows a basic chord sequence all the way through. Other versions use 
minor chords whereas i find it easier to: 

capo on 1st and play

B B, D D, G G, D D

it's then just a matter of working out the rhythm 

     B             D  G              D
Some-times, I  feel, I've got to,
B  D        G            D
    Run a-way, I've got to,
B  D        G            D
    Get a-way, from the pain,
         B             D          G
That you drive into the heart of me.

and so on...
