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.
For context if readers don’t know, there is a common game in writer circles where people take turns reading The Eye of Argon out loud, and if you laugh, you have to pass it on. People argued for ages about whether it was written by a troll to be deliberately bad. It’s that intense.
I now feel bad I ever played that game.
