This too shall pass we say. 

What do you do while this is passing?

Do you punish yourself with worry?

Drive yourself crazy with more imagined thoughts as if some god of fortune said if you punish yourself it will pass quickly or you will be rewarded. No

Endure it like a true stoic. Accept that it's your turn to face these misfortunes. Just like any other human being, fortune comes and goes.

Learn and build on character for it will serve you for a lifetime.
