To be 'melancholy' is a brand of sadness that is over thought, prolonged and can be caused by any reason regardless of its the magnitude. It's a very personal, heavy weighing sadness. It has similar
characteristics with
depression however, melancholy is an insidious sadness. It's more than simple desolation or dejection, melancholy feeds on pensive self
reflection in such a low state, reflecting lower and lower on itself until you can't see anything other than sadness.
