This is one of the most beautiful Dead by April songs, and the chords are built on 
the second version here.

I use capo on 6th fret, but that's optional.

Intro: C, Em, C, Em

Verse:

C
What I have in me
                Em
In my mind is you
                        
I would die if we were through

C
What I'm feeling now
                  Em
What I'm hading into
                         
I am lost in pain without you

C         D
(so cold, so alone)

Chorus:

C   D       Em
All I have is you
      D
It is all that I'm breathing for
C   D         Em
All I need is you

C, Em, C, Em

Verse:

C
All the nights I've prayed
                 Em    
must this all be untrue
                        
I am not prepared to be strong

C
I just can't belive 
            Em
I am losing you

Not prepared to carry on
                   
I can see you walk away 

C         D
(so cold, so alone)


Chorus:

C   D       Em
All I have is you
      D
It is all that I'm breathing for
C   D         Em
All I need is you
     G      D      C
I am losing you forever
     G       D         C
I am leaving ground forever

(forever)

Em              C
Distant so far, destiny's selecting me
Em                  C
I can't be strong, life is disconnecting me
Em  C
Now loneliness infecting me
Em                C                         D
Gone are the days you were there protecting me

D
(so cold, so alone)

C   D       Em
All I have is you
      D
It is all that I'm breathing for
C   D         Em
All I need is you
 
Now I can't make it through
     G      D   C
I am losing you forever
     G       D      C
I am leaving ground forever

C   D       Em
All I have is you
      D
It is all that I'm breathing for
C   D         Em
All I need is you

Now I can't make it through

(It is all that I'm waiting for, waiting for, waiting for)
