This song wasn't so hard to figure out!
I got this helpful trick from Ashfia15Bleach; in order to play the song, you just 
have to count the beat like this:

Em                 D      G                     C
1, 2, 3, 4 | 1, 2, 3, 4 | 1, 2, 3, 4 | 1, 2, 3, 4 | 

Alright, here it goes.

CAPO 1

Intro: Em D G C

VERSE ONE:

Em                    D
  I think you got the best of me
G               C
  You're sleeping  with the enemy
Em                  D     G             C
  You left me all alone, alone, alone, alone
Em                   D
  The beat drops, I'm  so low
G                    C
  My heart stops, I already know
Em                  D     G             C
  You left me all alone, alone, alone, alone


CHORUS:

    Em                             D
I'm sick and tired of the mess you made me
G
Never gonna catch me cry (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G                       C
You'll miss me 'til the day you die (Oh whoa whoa)
    Em  D          G  C
Without me, you're nothing (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G                       C
You'll miss me 'til the day you die (Oh whoa whoa)


Verse 2:
Em                      D
  I've let go, finally over you 
G                    C
  This drama that you put me through
Em                D      G             C
  I'm better all alone, alone, alone, alone
Em                Em (one strum - hold)
  The beat drops, you're so low
G                       C
  It's last call and it's gotten old
Em              D            G            C
  Now look who's all alone, alone, alone, alone


CHORUS:

    Em                             D
I'm sick and tired of the mess you made me
G
Never gonna catch me cry (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G                       C
You'll miss me 'til the day you die (Oh whoa whoa)
    Em  D          G  C
Without me, you're nothing (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G                       C
You'll miss me 'til the day you die (Oh whoa whoa)



BRIDGE:

C               G
  I trusted you, you were the first
D              Em
  Then you lied and it gets worse
C
  You broke me down
G
  Now just look around
D             Em (hold)
  Who's all alone? Who's all alone now?


CHORUS:

    Em                             D
I'm sick and tired of the mess you made me
G
Never gonna catch me cry (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G                       C
You'll miss me 'til the day you die (Oh whoa whoa)
    Em  D          G  C
Without me, you're nothing (Oh whoa whoa)
    Em                        D
You must be blind if you can't see
       G (hold)
You'll miss me 'til the day you die (Oh whoa whoa)
