Hey! this is really simple to play! i used these chords from ear. im not sure about the 
bridge but the rest sounds fine :)
the strumming is for the verse all down strokes:
Cadd9 (x32030@1)name="chord_320003@1">G         Em (022000@1)  D1,2,3 (xx0232@1)1,2,3,4,5 1,2,3 1,2,3,4,5

For the chorus all strums down:
Cadd9 (x32030@1)         G (320003@1)             Em (022000@1)            D1,2,3,4,5,6,7,8 (xx0232@1)1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8

for the bridge all strums down:
Am (x02210@1)            Em (022000@1)             Last D1,2,3,4,5,6,7,8 (xx0232@1)1,2,3,4,5,6,7,8  16x
