I DON'T KNOW IF THIS IS FINE, BUT I'M LEARNING TO PLAY GUITAR AND I'M NEW IN THE MUSIC.
 Use capo un the 4th Fret.

THE CHORDS ARE:  Dm, G, and A7... AND REPEAT IT..! 

                Dm              G
Are you really here or am I dreaming
          A7                Dm
I can’t tell dreams from truth
                  Dm                G
for it’s been so long since I have seen you
              A7                   Dm
I can hardly remember your face anymore

   Dm              G
When I get really lonely
         A7                    Dm
and the distance causes our silence
   Dm              G
I think of you smiling
         A7                Dm
with pride in your eyes a lover that sighs

REPEAT IT... AND THE CHORDS TOO...

If you want me satisfy me, if you want me satisfy me
If you want me satisfy me, if you want me satisfy me

Are you really sure that you’d believe me
when others say I lie
I wonder if you could ever despise me
when you know I really try
to be a better one to satisfy you
For your everything to me
and I’ll do what you ask me
if you’ll let me be, free

If you want me satisfy me, if you want me satisfy me
If you want me satisfy me, if you want me satisfy me
If you want me satisfy me, if you want me satisfy me
