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.
Okay, so this is not as dramatic as some of the other stories people are sharing, but Marilynne Robinson is one of my favorite authors and I have heard that certain folks looked down on her because she taught at a public university (The University of Iowa). smh.
