So the trick to this song is just to strum up and down non-stop 
throughout the entire song. I do believe this is 100% correct.
When you first play it try and play along with the song just to 
get a better sense of timing for your chord changes and strumming.
I know most of ya'll will be here because of the movie Warm Bodies.
So learn how to play and enjoy. By the way I played this on Acoustic.

So cold, I know you can't believe it

F
I've been alone too many nights 
C
Too proud to tell you when you're right
Em 
A little patience would have helped me then

A lot like the break has been the common standard

All the angels above the earth I prayed 
Em
Send this message right into her head

There's certain things in life I cannot take 
C
And I will wait
