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.
You know she is actively writing a detective series, right? They seem to be pretty popular, too. I haven’t read them but an avid reader I know said they were okay to good. She is still at her craft!
