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.
People say she inspired a whole generation of kids to read. Honestly, so much of that was marketing spin by her publishing company.
Those books were a publishing fad, but others came before her and after her. Kids were always reading. They just weren’t all reading the same thing.
