I realized that I have some emotional imbalanced disorder. I always feel sad whenever I watched a sunset.
Some of you may have also noticed that you find a seasonal fluctuation in your moods, feeling depressed only the day is about to end.

With our bright hours of sunlight in the daytime, it's no wonder we're happier this time of day.

The medical term for the season-long malaise that we fall into is seasonal affective disorder, or SAD.
