I can't get that last line either, but I do have some corrections to other lines in your Ethel Waters transcription:

Yet I'm in a jam, a terrible jam.

Oh, don't ask me am I blue
Why do you ask me am I blue?
Ain't these tears in these eyes telling you?
How can you ask me am I blue?
Why, wouldn't you be too,
If each plan with your man had [or "has"?] done fell through?
