I found this old favorite song of mine. Take it for what it's worth. A day-brightener, yes, a cure-all, no.
This beautiful song was used as background music in one of Charlie Chaplin's silent pictures over 70 years ago, which I believe was called "Modern Times". The song is called "Smile",and its melody is still recognized by many today.
Here are the lyrics:
SMILE by Chaplin, Parsons and Phillips
Smile, though your heart is aching.
Smile, even though it's breaking.
Though there are clouds in the sky,
You'll get by...
If you smile through your fears and sorrows.
Smile and maybe tomorrow.
You'll see the sun come shining through.
If you just light up your face with gladness,
Hide every trace of sadness.
Although a tear may be ever, ever so near.
That's the time you must keep on trying.
Smile, what's the use of crying?
You'll find life is still worthwhile
If you'll just smile, come on and smile.
If you just smile.
