How to write really good poems regarding sadness and loneliness?

Write from the soul. Pour all you're hurt feeling on to the page.

Personnify it, make it a torturer...
Relate it to enclosure,prison,dunjeon,a place that prevent 你 to the outside...
Relate Sadness to depression,river,tide,tear,moon,a frustration,an emotion that's 你 deserve.
你 can't escape sadness but if 你 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...
