I forgot to mention in my email that each chord shown is for 4 beats unless there is a superscript number at the side of it showing different. It is double strummed (i.e. two down strums per beat) and palm muted.
As it is in a minor key there is no way to play it in G, which is a major key, but if you really want to play the song that will be the incentive to learn new chords.
It is easier to play in Am with the capo on the 3rd fret if you want to keep to the original key but, as with any song, you really need to play it in the key that suits your voice, so you can move your capo to a position that suits you best.
I have a good backing track that my students use which will help you keep in time so if you want, and you let me know what key (or capo position) suits you, I can adjust the key and send a copy for you to work with.
