Really easy just play Em , Bm then G , G (or G9 )  
you can add relative chords between to fill it out more 


         Em      Bm        G   G9 
Theres a world outside 
Em             Bm             G     G9 
And I know cause Ive heard talk 
       Em        Bm          G      G9 
In my sweetest dream 
       Em      Bm         G      G9 
I would go out for a walk 

But I dont think Im ready yet 
Im not feeling up to it now 
Just not that steady yet 
And I dont need you telling me how 

Theres some happiness 
And my stone face cracks again 
Maybe sometime sooner or later 

But I dont think Im ready yet 
Im not feeling up to it now 
Just not that steady yet 
And I dont need you telling me how 

So if I leave my room 
Dont you tell me to lighten up 
Maybe sometime sooner or later 

But I dont think Im ready yet 
Im not feeling up to it now 
Just not that steady yet 
And I dont need you telling me how
