Intro:

e|---------------------|
        -|--1---1---1---1------|
        -|----0---0---0---0----|
        -|---------------------|
        -|---------------------|
E|--1-------3----------|


        Repeat the above a good few times using finger picking
        (a thumb comes in handy for the F note).

Rest of song:
        Most of the song just alternates between an F and a G.
        For the two tense "breaks" in the song, fiddle with an Am like so:

E|-3--2|
B|-1--1|
G|-0--0|
D|-2--2|
A|-0--0|
E|-x--x|

        Alternate between the two chords above for these breaks.
        And then you get to the "Me myself again" bit where the chords go:

        C, F, C, F, G, F
