Thats awesome, how such few words pour the feeling strongly. Love it:)

When I think about the word obscurity, I relate it with dark.. but obscurity is more like something that is unclear.. then I'm thinking.. something that is unclear can make things worst? so I'm thinking that perpaps, by obscurity you meant darkness can make the memories that are stuck with us to go deeper and deeper in us to haunt us until they stripe us away. Something like that.. I can't quiet explain it, but I like this senryu.

Wow you ave created such a powerful piece here. Nice job. I can relate to this feeling well. X
