I'm sure the names of the Drop C chords are off, but I just labeled them that way 
so both standard and Drop C match up.

Drop C:
G5 : x02200
C5 : 000230
D5 : 222100
E5 : 444200
Dadd4: Not too sure, but the sixth string is probably the 6th fret

G5 : 320033
C5 : x32033
D5 : xx0232
E5 : 022033

               G5        
Let's get to the point and all take our tongues out
                     C5
And not show off our scars not leave here with doubts that
G5                                      D5 
Things in life well they could've been easier
                       E5
And let's make sure we fought for all that we leave with
                  C5
And lessons we're taught make sure we believe them
             G5                                            D5
And promises kept all turn into secrets we'll keep to our graves

Get down on your knees when
 

Pre-Chorus:
         C5         G5                 D5
You feel sure the path ahead is about to end

You can never stop or you don't exist
          C5             G5
If you've walked your shoes away
          D5
Then just stop here awhile and just sit here with me and just


Chorus:
C5 G5
Hold On
              D5    E5
Tell me we'll hold on
C5
To today
G5
To tonight
D5
To the morning
         C5 G5 
And just hold on
          D5    Dadd4E5
Tell me we'll hold on
C5
Cause you feel
G5
Cause you breathe
D5
Cause when hurting
We are worth it
We can hold on


Interlude: G5

                       G5
And we've all seen the road

That we all walked to get here
                    C5
It's lined with the stones that we cast in our youth
                     G5
May they glow like a coal

And keep passion inside us
                 D5
Reminding though young and in love we're all fools
                     E5
But the time that we spent

In arms and in longing
                C5
Can rewrite the pages our fathers left here
                  G5
From a passage of hope and an act of conviction
            D5
To letters unsigned and unsent out of fear


Pre-Chorus:
          C5         G5                 D5
You're so sure the path ahead is about to end
         C5          G5
Will you throw this all away
        D5
Or keep pace with a stride that stays even with mine
And we'll
