Still looking for help on the next to last line of Ethel Waters, "Am I Blue." The MP3 is at the link provided.

Correction: Clark and Akst wrote the lyrics and published the sheet music in 1919. The musical was "On With the Show," with Ethel Waters.
Also in the show was "Birmingham Bertha."
Original sheet music lyrics:

Lyr. Add: Am I Blue
Clark and Akst, 1919

I'm just a woman, a lonely woman
Waitin' on the weary shore.-
I'm just a woman that's only human,
One you should be sorry for.-

Got up this mornin' along about dawn,-
Without a warnin' I found him gone.-
Why should he do it? How could he do it?
He never done it before.-

Chorus:
Am I blue? -
Am I blue? -
Ain't these tears in these eyes - tellin' you? -
Am I blue? -
You'd be too -
If each plan - with your man - done fell through.
Was a time - I was his only one, -
But now I'm - the sad and lonely one, -
"Lawdy," Was I gay? - till today, -
Now he's gone - and we're through, -
Am I blue? - Am I blue?

It's aggravatin' to stand here waitin'
Waitin' for a triflin' man. -
It set me hatin' to stand here waitin'
Suicide's my only plan. -
I think it's awful, his treatment of me, -
It's most unlawful how mean he can be -
I can't forget him, I'm bound to get him,
I'll run him down if I can.
