it's fine to post here. you can go pretty dark and gritty without anyone calling you out. i've posted some pretty triggering stuff myself, though some i've deleted (not because i was told to, more because i tend to post things spur of the moment and sometimes some things are better kept away from a community of self-harmers).
anyways i like these kind of poems, playing with language is always fun, even though i don't bother doing it as much as i'd like.
you should post more so. it would be fun to have something more than my own gibberish to read.
