I heard this song yesterday, and just had to play it! I tried to find the chords, 
but I couldn't so here are the chords I played by ear. I think they are ok! :)

Intro: Em G D A

EmI'm (022000@1)running around
               GThink (320003@1)my foots on the ground
      D (xx0232@1)                         ABut (x02220@1)I can't get it out of my head
     EmI've (022000@1)brought my sword
        GOf (320003@1)this I'm sure
     DI'll (xx0232@1)use it on myself instead

And it's all fine
I know I'm blind
I feel my heads in a different time
Days too dark
Nights too bright
I think I'm wrong when I know I'm right

Chorus: 
DNever (xx0232@1)knew I'd love so much
GNever (320003@1)thought my heart could crush
BmI (x24432@1)lost that war
A7I (x02020@1)lost that war

DI (xx0232@1)left my armor back at home
GComing (320003@1)back with broken bones
BmI (x24432@1)lost that war
A7I (x02020@1)lost that war

I thought that love
Was just a bus
Waiting for your damn stop to come up
Then you're out in the cold
You feel so old
It left you there
And it stole your coat
But it's all fine
I know I'm blind
Trusted you with my heart one time
Days are long
Nights are pain
Now I'm back in that bus in the rain

Chorus:
DNever (xx0232@1)knew I'd love so much
GNever (320003@1)thought my heart could crush
BmI (x24432@1)lost that war
A7I (x02020@1)lost that war

DI (xx0232@1)left my armor back at home
GComing (320003@1)back with broken bones
BmI (x24432@1)lost that war
A7I (x02020@1)lost that war

Fm (133111@1)                          EmWanna (022000@1)take my pages read them through so you can see
Fm (133111@1)                                 EmAll (022000@1)my words and darkness they don't leave no room to breath
A (x02220@1)                             EmHeartbreak's (022000@1)contagious loves become my enemy
G (320003@1)                                  AYou (x02220@1)think you can change it, but the war is changing me
