season of blossom
of course i have to recommend "a cruel god reigns"
Not sure if this what you mean...but this story is about schizophrenia, although according to one commenter it technically isn't "accurate", but it does portray it.

Probably one of the most realistic portrayals of the effects of SA. Great story but very tough read. I recommend taking fluff breaks if things get overwhelming.
Guys what are some good stories that actually portray mental health accurately and the character doesnt automatically become healed in like 1 chapter or by the power of love everything automatically goes away
