You'll have to listen to the song while you're practicing to fully understand how to 
play it. THE VERSE IS PLAYED IN 4/4 TIMING where as THE BRIDGE AND CHORUS ARE PLAYED IN 
3/4 TIMING, so you need a good enough understanding of music theory to play the song.

C (palm mute and pluck throughout the verse at a steady pace)
I'm gonna take a stab at this
sure you will be alright
make a decision with a kiss
baby I have false spite

(The bridge is pretty straight forward, just remember that it is in 3/4 timing!)
Dm (xx0231@1)              GAnd (320003@1)when I trek alone back home
Dm (xx0231@1)                       GI (320003@1)make sure I trek in the snow
DmWould (xx0231@1)I fall?

C (same as verse before)
Tissue and bones, it was a trick
this isn't a gun-fight
checking it off of my list
unable to rewrite

(Bridge, same as before)

Dm (xx0231@1)                           GFive (320003@1)years cast once and far alone
Dm (xx0231@1)                  Ghope (320003@1)I'm ready, able to make my own
DmGoodbye (xx0231@1)
(For this part, the chorus, you play the Dm for 2 bars, as well as the Am and G. This 
part is also in 3/4 timing.)
Repeat 4 times

AmThey (x02210@1)go, we go
GI (320003@1)want you to know
Dmwhat (xx0231@1)I did, I did

(For this next part play the Dm for 4 bars, and the Am and G for 2).

Am G Dm, Am G Dm

(repeat chorus twice, the second time you play Dm for 4 bars).

AmThey (x02210@1)go, we go
GI (320003@1)want you to know
Dmwhat (xx0231@1)I did, I did

After the last chorus is a play off using the chords from the chorus (in that same order).

I prefer to end on a Dm because it sounds jazzy, and it fits nicely, but go ahead and 
end on Am if you like.
