The Day starts off Dark and depressing, but it ends with Light.
Thus, trouble should not be seen as a chance happening, nor as an excuse for depression. It should rather be viewed as an opportunity opportunity for a new beginning. If we can understand that this trouble is only temporary, just another stage in life, we can face it better.
G-d gives us the Night, with its confusion and chaos, however, He never intends it to continue forever. Daylight, joy and happiness will follow afterwards. Indeed, without this Night, Day cannot emerge.
So, with each Night, with each new trouble, a new age is opening up in our lives. Creation is beginning again.
