Personnify it, make it a torturer...
Relate it to enclosure,prison,dunjeon,a place that prevent you to the outside...
Relate Sadness to depression,river,tide,tear,moon,a frustration,an emotion that's you deserve.
You can't escape sadness but if you retain for too long, nobody will never listen to it. The world couldn't take it our even take it as an accomplishment,reason?
They are destructif,bully and wish a world an ultimate end...
