Pre-Chorus:

e|-3-----3-----3-----3-----6-----6-3-----6-----3-----3----------|
B|---4-----4-----4-----4-----4-------4-----4-----4-----4----3~--|
G|-----5-----5-----5-----5-----5-------5-----5-----5-----5--4~--|
D|----------------------------------------------------------5~--|
A|----------------------------------------------------------5~--|
D|--------------------------------------------------------------|

Chorus:
This is really weird cause first the guitar is plays these chords
Twice
e|-------------|
B|-------------|
G|-8--10-12--3-|
D|-6--8--10--1-|
A|-6--8--10--1-|
D|-6--8--10--1-|
but for the second part of the chorus they play it like this

D|---------|
A|---------|
F|---------|
C|-4-6-0-3-|
G|-4-6-0-3-|
C|-4-6-0-3-|

BET YA NOTICED SOMETHING WRONG!
yeah this song is probably in Drop C but i don't think you'd tune your guitar a whole 
down just because there's ONE lower chord, so if you want just play it like the first 2 
again.

"THOUGHT THAT I HAD SAAIID GOOOD BYEEE"

e|---------------|
B|---------------|
G|---------------|
D|-6666666655555-|
A|-6666666655555-|
D|-6666666655555-|


Now repeat everything for the next Pre-Chorus and Chorus

Bridge:

Guitar 1 just lets this chord ring

e|---|
B|---|
G|---|
D|-6-|
A|-6-|
D|-6-|

Guitar 2 plays this as needed

e|----11--------11--|
B|----11--------11--|
G|-12----12--12-----|
D|------------------|
A|------------------|
D|------------------|


Now just repeat the chorus
and then repeat the lead parts of the bridge for the outro.
that's it.
