This is pretty much it, you can play a few bars of (Am, C, G?D,C,G) if you like to get 
song going or just go straight into it, either way works.
The same at the end: either stop on the final G or repeat (Am, C, G?D,C,G)  ?Until 
Hope it helps.

Am              C                      G
I know that you are feeling bitter,
D         C                        G
What I said last I didn't mean,
Am                 C              G
And now that I'm a little better,
D         C                      G      D
This is what I'd like to say:


Ch
G         D         Am7            C
Babe I already miss you
         G        D           Am7             C
SweetHeart I already miss you
          G       D           Am7           C
SweetEyes I already miss you
D                    C                             G
And you only just walked out the door.

You know I hate talking on telephones,
D        C                        G
I'm so sorry it?s just my way,
Am                   C               G
And know that I'm a little older,
D         C                     G        D
