hi! this is one of my favorite songs from the band, and I just got around to tabbing it out :) the other version
is great, btw, this is just a different/simpler sound. 
listen to the song for rhythm stuff (it shouldn't be that hard) 
I'm not really sure on the Em, but it sounds alright if you're playing it alone. if you have a suggestion, 
don't hesitate to tell me in the comments!

Intro:
G C D Em
G                    C
Happier than I was before
             D
I'm hoping now you're here
              Em
I'm able to handle it
   G                              C
I'm drifting along coastlines and shores
              D
On stepping stones
                   Em
Just building my confidence
Pre-chorus: 
D                         Em
 I'm making visits to the sea
    G                C
For visions of you and me
D                            Em
 And when I get there I will row
 G                       C
Oceans between me and my home
Chorus: 
      G
'Cause I
I don't wanna live
            C     D
Don't wanna die alone
        G
And it's true
                              C
There's nothing out there for me 
         D
without you
   G                         C
I'm making ends meet fixing up cars
           D                              Em
Yeah it's the only thing that's keeping my mind awake
 G                           C
Drifting between my favorite bars
          D                            Em
All those nights I should have been there for you
[Pre-chorus]
[Chorus]
Bridge: 
Em                       C
 And there's nothing that I can say
G             D
 I gave up my life that day
Em                C                  G          D
Making sure I was doing just what it takes
Em             C
 A blur of a life lived fast
G                     D
Yeah my heart stopped when you passed
Em            C                G         D
But there is one thing I wanna say
[Chorus]
(you can end on either D or G, both sound good)
