Really easy just play E5 , B5 then G5 , G5 (or G5 )  
you can add relative chords between to fill it out more 


         E5      B5        G5   G5 
Theres a world outside 
E5             B5             G5     G5 
And I know cause Ive heard talk 
       E5        B5          G5      G5 
In my sweetest dream 
       E5      B5         G5      G5 
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
