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 didn’t just have a problem with fanfiction. She tried ruin people’s busineses and even involved lawyers.
I didn’t know about the alcoholism and OCD, huh.
