Speak by J Miley is a mental health story. I haven’t read it yet but I’ve heard it’s a good story and Jen always represents different things quite well.
The Triangle by Ladybug is a good SA survivor story.
As for other conditions, I don’t have anything to recommend because most of the stories I’ve read don’t delve into such topics much if at all.
I have an upcoming story called Markings of the Mafia (it’s not actually a mafia story) where a lot of the characters suffer from different things: hemochromatosis, chronic fatigue, social anxiety and some of them are also SA victims. Just thought I’d let you know in case you ever want to read it in future.
