The Milk Carton Kids - As It Must Be chords

This is my first tab, so bear with me, but this is more for singing along with the 
song, I'm not able to do all the picking but I worked out some basic chords that 
make the song easy to play :) If you know the song you'll be able to easily tell 
where the chords change. Hope this is useful, do give me suggestions if I can improve it. 

Its basically 
Am G Am G D 
Am C G D

(I like to play it with a capo on 4 but it depends what suits your voice.)

Maybe we'll come out of this 
Maybe we'll come out of this unscathed 
Just like the story said 
Ever after we shall be okay 

I know that you don't know where we go when we go 
I know that it's hard so we can't go alone 

Let it run right over you 
Let it run like water to the sea 
Nothing lasts forever darling 
Everything is as it must be 

I know that you'd never let me go on my own 
I know that I'll never make it alone 

Look at your reflection 
Casting your own image in the stream 
Though it moves right through you 
Something of you soul remains within
