I've seen a few tries at the chords, but none have really sounded quite right to 
me. This is what I play

The brackets are for repeats

Em D C D (Arpeggiated)

Em           D
I'm sick and tired of
C              D
Hanging out my window,
Em                    D
I've learnt from past experience 
C                       D
Rain can't make flowers grow,

Em                  D
Friends don't stick around
C                     D
They go which way the wind goes,
Em                    D
You're never safe and sound 
C                       D
?Til all your [doors are closed]

G           
[When you're awake 
Em
On your own,
C.                 D
Shadows turn into ghosts]

(Repeat Em pattern until G pattern on chorus)
Ooh ooh

Soon it will all fall apart
And their roads will have no way,
And you'll be the one laughing as
Their fences fade away,

And instead of being left there,
Feeling all alone,
Break down the house you made of match sticks
And set fire [to their throne]

G
[When you're awake 
On your own 
Shadows turn into ghosts,]

(Em pattern)

[Home becomes what you're scared of the most]
Em
When shadows turn into ghosts 
It?s what your scared of the most

G
[I'm pulling pictures off the wall 
Watching smiles as they fall] x3
I?m pulling pictures off the wall (back to top)

[When you're awake 
On your own 
Shadows turn into ghosts,]

[Home becomes what you're scared of the most]
When shadows turn into ghosts 
It?s what your scared of the most
