Ok so I couldn't find any of the chords online so i figured it out myself.

It's written in G

so the intro is 
C G D Em

Verses (some are same as intro)
G D Em

Chorus
G Em Bm D

Interlude
G Em
C D

When you were locked up in your room alone
neglecting even just to touch the phone,
salty tears rolling down your cheeks
like they had done any times before,
did you fear that every time you speak
would be the very final word that creeps
between your teeth and off your tongue before
you collapse from a broken heart?

I've gone half crazy worried about you, about you...
My left eye's gone lazy worried about you,

Every morning you were petrified
that nobody could ever pacify
the sinking feeling that you had deep down
that kept your heart on hold?
My shoulder was an easy place to hide,
but I didn't mind because I could pass the time
counting the thousand little lies you kept
inside of your broken heart.

I've gone half crazy worried about you, about you...
My left eye's gone lazy worried about you, about you...

Every word you say is self-directed
and I think that that is tragic.
And every time you open up you mouth to speak
it's self referenced, and that's tragic.
You don't have to see the world to know it's true, 
you don't have to see the world to know that it keeps turning. 

I've gone half crazy worried about you, about you...
