I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
She’s the only author I’ve ever strongly considered getting a tattoo to honor. Her work changed me in a way I can’t explain. She’s so incredible and I hate that so much is lost.
