joyful sadness

hi, today i want talk about a type of sadness that i call " joyful sadness".it means for me, a colorful sadness that doesn't need to be in dark room or wear black clothes or even have sad face , it's just feeling sad without loosing hope or the ability to feel and see the beauty around you.the sadness that gives you the mood to listen to chillout music or to go either to the sea or a walk in forest , to be in nature.sadness for me is not to cry or hate fate or even blame the other , it's Self-examination ,revision of my mistakes, to be more sure of my decisions and thoughts.the ability to save what remains for me, to give to myself a lesson , to know the wisdom of these experiences.
