The following poem by  Ella Wheeler Wilcox (November 5, 1850 – October 30, 1919 is sad but true.  For those who suffer clinical depression, the world is hard on them, while those who have a sunny disposition fare better.  All, however, suffer pain.

Solitude

Laugh, and the world laughs with you:
Weep, and you weep alone;
For the sad old earth
Must borrow its mirth,
It has trouble enough of its own.

Sing, and the hills will answer;
Sigh, it is lost on the air;
The echoes bound
To a joyful sound,
But shrink from voicing care.

Rejoice, and men will seek you;
Grieve, and they turn and go;
They want full measure
Of all your pleasure,
But they do not want your woe.

Be glad, and your friends are many;
Be sad, and you lose them all;
There are none to decline
Your nectared wine,
But alone you must drink life's gall.

Feast, and your halls are crowded;
Fast, and the world goes by;
Succeed and give,
And it helps you live,
But it cannot help you die.

There is room in the halls of pleasure
For a long and lordly train;
But one by one
We must all file on
Through the narrow aisles of pain.
