So for the "Maybe" part it will be easier if you play starting with the Am as x77555 to just work your way 
down. I'm a little unsure about what is minor or major in that part so feel free to leave suggestions!

[Intro]
        Am                          F
You can break down my lights and my doors
      G                        C
But I won't let you back in no more, no more
Am           F                    G        E
 I'm sick of getting stuck in the same routine again

[Instrumental] Am   Am   E   E     x2

[Verse 1]
Am
 Five nights, it shouldn't seem so long
C
 But it takes forever when you all about it wrong
Am                                  F          E
 These halls are lined with blood I can't have on my hands
Am
 These walls they seem to call my name
C
 But I refuse to be another puppet in your game
Am                                 F             E
 Your eyes are dead inside but tonight I leave alive

[Chorus]
        Am                          F
You can break down my lights and my doors
      G                        C
But I won't let you back in no more, no more
Am           F                    G        E
 I'm sick of getting stuck in the same routine again
       Am                F
Tie me up, put me into a suit
         G                  C
But I'll never ever be like you, no
Am           F                     G       E
 I know what happened here and you can't erase your past

[Instrumental] Am   Am   E   E

[Verse 2]
Am
 I've done what I can to try to hide
C
 But even you can tell who I really am inside
Am                                     F                E
 And it's not my job to watch you, I'm leaving here tonight

    Am        G#m             G      F#       F              E             D#         E       
But maybe one day you'll find humanity, until then don't you dare say that we are the same

[Chorus]
        Am                          F
You can break down my lights and my doors
      G                        C
But I won't let you back in no more, no more
Am           F                    G        E
 I'm sick of getting stuck in the same routine again
       Am                F
Tie me up, put me into a suit
         G                  C
But I'll never ever be like you, no
Am           F                     G       E
 I know what happened here and you can't erase your past

[Bridge]
F                    C                                Am                     E
I crave the light of day, but I've been keeping you away. It's driving me insane (It's driving me insane)

[Chorus]
        Am                          F
You can break down my lights and my doors
      G                        C
But I won't let you back in no more, no more
Am           F                    G        E
 I'm sick of getting stuck in the same routine again
       Am                F
Tie me up, put me into a suit
         G                  C
But I'll never ever be like you, no
Am           F                     G       E
 I know what happened here and you can't erase your past

Am        G#m             G     F#
Maybe one day you'll find humanity...
