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 あなた to the outside...
Relate Sadness to depression,river,tide,tear,moon,a frustration,an emotion that's あなた deserve.
あなた can't escape sadness but if あなた 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...
