Out Of My Head Chords

I was watching fastball perform this song live and 
I couldn't find a tab even close to how he played the song. 
I couldn't figure out a few chords, so if you do please enlighten me. 
This is a really simple version of this song which is good cause 
I"m still pretty new.

Verse
G                       Bm
  Sometimes I feel like I am drunk behind the wheel
     C            G
The wheel of possibility
   A          D
However it may roll 
G                               Bm
  Give it a spin, see if it can somehow factor in
   C                     G
You know there's always more than one way
   A          D                 G
To say exactly what you mean to say



Chorus:
(G)             D                     Em7
Was I out of my head, was I out of my mind?
                      G      C
How could I have ever been so blind?
                     G
I was waiting for an indication
A             D       
It was hard to find
G                   D                     Em7    
Don't matter what I say, no matter what I do
                    G         C
I never mean to do bad things to you
                G
So quiet but I finally woke up
A                      D                 G
If you're sad then it's time you spoke up too
