I think its more accurate than the existing one, enjoy! : )
It's very easy, just play 
C, Em7, Am, F, C, Em7, F, C 
and repeat though out the whole song.

Intro:
C, Em7, Am, F x2

C            Em7
is it over now
       Am                      F
do we really have to say goodbye
C        Em7           F              C 
does it mean that we can't talk anymore
C            Em7
cos I still love you so
           Am                      F
cos I didn't mean to break your heart
C        Em7           F              C 
if only you knew why I had to let you go


is it over now
feels like it's the end of the world
I don't really wanna try to get over you
cos still see your face
feel your breath everywhere I go
don't think I'll ever find someone just like you

                     C Em7
I thought we could last
     Am           F
be together forever
                C  Em7
but we didn't last
             F          C
we sure did put up a fight
         C        Em7
now it hurts so bad
      Am            F
with you out of my life
C     Em7    F      C
is it really over now


Guess it's over now
cos I'm sitting here all alone
someone is knocking but it won't be you at my door
letting go is never easy
I've been learning it the hard way
I've been counting every minute and second
since the day you left

I thought we could last
be together forever
but we didn't last
we sure did put up a fight
now it hurts so bad
with you out of my life
is it really over now

C     Em7    F      C
is it really over now
