Chords are a tad different than standard (mostly just the Bm):
     G   Bm   Em   D/F#  C
E|---3----3----3----3----3----|
B|---3----3----3----3----3----|
G|---0----2----0----2----0----|
D|---0----x----2----0----2----|
A|---2----2----2----0----3----|
E|---3---------0----2---------|

This style of playing in the key of G should be fairly well known, though, but it's for 
who don't know it. :P


Verse 1:
 G            Bm
I'll admit to who I am
    Em             D/F#
The day I come to understand
   C
I haven't got a clue
      C                         G     D/F#*    Em   D/F#*
Been searching for a few years now

Verse 2:
     G             Bm
Well if I don't repeat myself
      Em                D/F#
Then I'll change into someone else
     C
Well I don't quite know who
      C
Been searching for a few years now

Chorus:
     C
I'm over it
       D/F#
Yeah behind me now
          Em         G
I'm just over it
 C
Over it
          D/F#
Yeah I'm finding out
          Em         G
I'm just over it
    C                   D/F#
No, I don't know what's over just yet
       Em                G                C
But I won't go slow and time can let the mind forget
              D/F#*      G
Don't tell me you don't know
D/F#* Em
Already
               D/F#*   G
(Don't tell me you let go
D/F#* Em
Already)

Verse 3:
G                  Bm
I'll protect your universe
    Em             D/F#
Or make a mess to make it worse
 C
Time will only tell
 C
You and no one else so

Bridge:
             C                            D/F#
You say you made up your mind and you've finally decided
     Em
But those that helped you choose
 C                    D/F#            Em                C
Haven't the slightest clue as to the magnitude of what you're about to lose

Verse 4:
      G                   Bm
I'm guarded and therefore I can endure
   Em
A little bit more
        D/F#
Just a little bit more
 C
Than some people would
        C
If I'm not misunderstood
                 G                   Bm
It's still an attempt to be egoless while self-assured
    Em                   D/F#
If I'm still unsure that I'm pretty sure
     C
That I am pretty good
 C
God, you know I'm good and


Side-notes:
- D/F# can be interchanged with a regular D major chord except for the starred ones 
sounds better, lol)

- Every chord should be around the place that they're actually played except for the 
in the chorus because there's no space :\

- The parts of verses where there's two lines of C's can be replaced with:
     C          Em
     C          D/F#
  Your choice on which you prefer. However, the verse 1 seems to be just C, at least.
