If you want Classical Greek insanity look up fan content for the book "The Song of Achilles" by Madeline Miller. The book itself is novel about Achilles and Patroclus, where the author has turned him into a guy who acts like a swooning and helpless waifu. Maybe look also for fan content for the game Hades, while the majority is centred around the game characters, there are also a few fan OCs around.
On a side note, I think the majorty of SJW artists can only read (longer) fanfiction because it’s already about characters they're invested in. The Iliad, the Divine Comedy, and every other classic is just too long and dry (and not openly gay and/or trans enough) for them to hold their attention span and make them care about the story and characters. I also think a reader of the classics needs a reading comprehension way higher than most SJW can call their own.
