OK this song is really simple.
Capo is needed on the first fret with guitar in standard tuning
 Enjoy Bieber Fans
          DI (xx0232@1)never thought that it be easy
          ACause (x02220@1)we both so distant now
          EAnd (022100@1)the walls are closing in on us
And we're wondering how
        DNo (xx0232@1)one has a solid answer
            ABut (x02220@1)just walking in the dark
             EAnd (022100@1)you can see the look on my face
It just tears me apart
        D (xx0232@1)                             ASo (x02220@1)we fight (so we fight) through the hurt (through the hurt)
        EAnd (022100@1)we cry (and cry and cry and cry)
        D (xx0232@1)                        AAnd (x02220@1)we live (and we live) and we learn (and we learn)
        EAnd (022100@1)we try and try and try and try
        D (xx0232@1)                  ASo (x02220@1)its up to to you and its up to me
         EThat (022100@1)we meet in our middle way
On our way back down to earth
D (xx0232@1)                     ADown (x02220@1)to earth down to earth
E (022100@1)    On our way back down to earth

REPEAT CHORDS THROUGHOUT IN SAME WAY... THE "we fell so far away..." bit may be 
but I havent figured that out yet sorry :( any suggestions just let me know :)

Mama you were always somewhere
And daddy I live outta down
So tell me how could I ever be normal somehow
You tell me this is for the best
So tell me why am I in tears
So far away and now I just need you here

So we fight (so we fight) through the hurt (through the hurt)
And we cry (and cry and cry and cry)
And we live (and we live) and we learn (and we learn)
And we try and try and try and try

So its up to to you and its up to me
That we meet in our middle way
On our way back down to earth
Down to earth down to earth
On our way back down to earth

We fell so far away from where we used to be
Now we're standing and where do we go
When there's no road to get to your heart
Let's start over again

So its up to to you and its up to me
That we meet in our middle way
On our way back down to earth
Down to earth down to earth
On our way back down to earth
(back down to earth - repeat)

I never thought that it be easy
Cause we both so distance now
And the walls are closing in on us
And we're wondering how.
