Nobody Knows It But Me chords by Kevin Sharp

This is how I play this and all the words are correct. These chords work for me.

The G I use is played adding the 3rd fret of the B string and using the
pinky to play the high e. I don't know the exact name, it's just shown as G on the
chord charts I could find,

G (W/D) is a walk down from the G to the Em


D
I pretend that I'm glad you went away,
D
And these four wall's close in more everyday
        D
And I'm dyin inside, and nobody knows it but me.

D
Like a clown I put on a show,
D
The pain is real even if nobody knows
        G (W/D)
And I'm cryin inside, and nobody knows it but me.

D
Why didn't I say the things I needed to say,
D
How could I let my angel get away.
D
Now my world is just a, tumbling down,
Cadd9
I can see it so clearly, that your nowhere around.

CHORUS:

D
The nights are so lonely the days are so sad, and
D
I just keep thinkin about the love that we had
        G
And I'm missin you, and nobody knows it but me

Interlude: G (W/D)

D
How blue can I get, you can ask my heart
D
Just like a jigsaw puzzle it's been torn all apart
          D
A million words couldn't say, just how I feel
Cadd9
A million years from now you know, I'll be lovin you still

Repeat Chorus
