Lyrics from the sheet music in the Levy collection at Johns Hopkins University:


I’LL NEVER SMILE AGAIN
Words and music by Ruth Lowe.
Published by Sun Music Co., Inc., New York, 1939.

VERSE: You loved me in the past,
But our romance didn’t last.
You thrilled me with your kiss,
Darling; now I promise this:

CHORUS: I’ll never smile again, until I smile at you.
I’ll never laugh again; what good would it do?
For tears would fill my eyes; my heart would realize
That our romance is through.
I’ll never love again; I’m so in love with you.
I’ll never thrill again to somebody new.
Within my heart, I know I will never start
To smile again, until I smile at you.

There are lots of recordings of this song, but I didn’t find one where the verse was sung.
