snape fics

can anyone recommend me some rlly angsty snape/sirius fics?? i reallllly like the ones where Snape is trans (FtM) but that’s not a requirement, just a bonus! i’m not opposed to other ships either i just mainly want it to be angsty as fuck like rip out my heart and throw it in the meat grinder :)

EDIT: i AM however opposed to snape/harry, hermione or just ANY of his students. not judging those who read it, just not my thing loves xx
