This is an easy version, and it sounds about right!

[Intro]
A E D A x2


[Verse 1]
A
One day I woke up
E
I woke up knowing
D                       A
Today is the day I will die
E
Went to the park and
D                     A
Enjoyed that one last time
C#m
I called my mother
C#m
Told her I loved her
D                     A
And begged her not to cry
A
I wrote a letter
E
I said I'd miss her
    D             A
And I'd sign that goodbye

[Bridge 1]
              E                  D
You know that happiest day of my life
            E                  D
I swear the happiest day of my life
                   A
Is that day that I die


[Chorus]

A                E
Can you feel the cold tonight?
Bm              D
It sets in, but it's alright
A               E
Darkness falls, I'm letting go
Bm                         D
All alone, but I feel just fine

A E D A x2

[Verse 2](same chords as verse 1)

A
We took a drive and
E
We drove through DC
D                    A
To see the places we lived
A
Long conversations
E
We talked of old friends
D                     A
And all the things we did
C#m
Summer nights
E
Drunken fights
D
Mistakes we made
D
Did we live them right?

[Bridge 1]
             E                  D
You know the happiest day of my life
            E                  D
I swear the happiest day of my life
                  A
Is the day that I die

[Chorus]
[Bridge 1]
             E                  D
You know the happiest day of my life
            C#m                D
I swear the happiest day of my life
             E                  D
You know the happiest day of my life
                  A
Is the day that I died

[Chorus]
[Bridge 2]
A             E
Did I live it right?
                  D
I know I lived it right
              A
Did I live it right?
A             E
Did I live it right?
                  D
I hope I lived it right
              A
Did I live it right?
         *~*~*

I got confused in Bridge 2, but it sounds right.
