It's easy to fool people about how we really feel. Simply wear a deceptive smile or hum a cheerful song like this one that was very popular during World War I and many years afterward:

What's the use of worrying?
It never was worthwhile,
So, pack up your troubles
In your old kit-bag
And smile, smile, smile.

Those words, written by British vaudeville actor George Powell, were set to a cheerful melody by his piano-playing brother Felix. It earned them $60,000.

Yet one day years later, Felix sat down at a piano and played his well-known melody "Smile, Smile, Smile." Then he went into a room where he was all alone and shot and killed himself.

Troubles can't be packed away and magically forgotten. A smile and a song may camouflage deep unhappiness, but only God can lift the burden of gnawing worry from our hearts. Knowing that He cares for us, we can cast all our anxiety on Him (1 Pet. 5:7). If in our difficulties we trust in the Lord as our strength, He will do even more than give emotional relief. He will enable us to rejoice (Hab. 3:17-19).  — Vernon C. Grounds
