Everyone else was way off with this song. Here's how it really goes.
Drop D Tuning - Key of F
Most of it is power chords.

Intro:
D   G-Bb (repeat)

Verse 1:
Dm (xx0231@1) I think im breaking out
C (x32010@1) Im gonna leave you now
Bb (x1333x@1) Theres nothing for me here
     F (133211@1)    C/EIts (x3111x@5)all the same

And even though I know
That everything might go
Go downhill from here
Im not afraid!!!

 D (xx0232@1)                         FWay (133211@1)away away from here ill be
Bb (x1333x@1)                     F/AWay (x03211@1)away away so you can see

Anything

Bridge:
On the light part it's back and forth between D and Bb.
On the heavy part it walk up: D E F G Bb

If you've seen versions one and two, they're wrong. This is the correct way to play it.
