The feeling of misery/melancholy/depression that we all feel at some point, that is painful, yet necessary for us to feel the opposite, happiness.
I was overcome by sadness when my puppy died, but I knew it was times like this that made it possible for me to feel happiness.

Seasonal affective disorder (SAD) is a type of depression that's related to changes in seasons — SAD begins and ends at about the same times every year. If you're like most people with SAD, your symptoms start in the fall and continue into the winter months, sapping your energy and making you feel moody. Less often, SAD causes depression in the spring or early summer.
