Chorus:
                        G                           D
Well, you only need the light when it's burning low
              A                       Bm
Only miss the sun when it starts to snow
               G                           D       A
Only know you love her when you let her go
                      G                            D
Only know you've been high when you're feeling low
              A                          Bm
Only hate the road when you're missin' home
               G                           D
Only know you love her when you let her go
A
  And you let her go

Bm                            G
Staring at the bottom of your glass
        A                          Gbm
Hoping one day you'll make a dream last
                  Bm              G          A
But dreams come slow and they go so fast

You see her when you close your eyes
      A                         Gbm
Maybe one day you'll understand why
               Bm            G        A
Everything you touch surely dies

Staring at the ceiling in the dark
         A                     Gbm
Same old empty feeling in your heart
                    Bm              G       A
'Cause love comes slow and it goes so fast

Well you see her when you fall asleep
             A                  Gbm
But never to touch and never to keep

And you dived too deep
