I'll edit this when i've figured the whole thing out, didn't take me long actually.
Very easy!
Ajust capo wherever is comfortable for you:), if you're playing guitar.
Same chords apply to the piano (as the original song)
***Chords used: G, Em, D, C/ Em, D, C, A/ G, Dm, C, A.
G              Em                           D
I wanna run away, somewhere far and somewhere safe.
                        C
So scared of this place.
G                                               
Cause you don't even know me.
Em                         D                                                              
You don't even care that i've been lonely, and tired 
 C
of fighting in the den of the lion where I won't even try.
Em                                               D
In the den of the night I wait, Early morning and I still haven't got some sleep.
C
Call me crazy, Call me Baby, You can call me weak, 
A
You don't even know, No you don't even know..
Em                                                           D
That the weight of the world on me, I've been there and back again and it seems to me,
C
The a promise isn't something you keep,
A
and a secret never lasts, it only sees what you see... 
(CHORUS)
G
Cause it's a cruel cruel ride,
        Dm
and if you want to come inside,
           C
You better sit up and close your eyes,
            A
and hold on for dear life.
         G
Cause if you don't,
          Dm
You will surely loose your mind,
          C
But I won't. 
Hope this helps for now! :D
