Sadness is one of the most complex emotions, arising from any of a variety of different circumstances and meaning only one thing: a loss of heart. Sadness tinges all emotions. Whether found with fear, hope, anger, or simply the depths of soul-crushing despair, it is in sadness that we find how deeply we can fall... and whether we will ever find the strength to rise again.
