I saw this on TV in the early 80s, maybe late 70s. In English, in color, possibly an episode of a TV series.
A woman is hearing voices. She might have been an inmate of a prison or an asylum. The voices are whispering, “You must die” and calling her by her name, which was Celia or Ilia or something like that. Compelled by the voices, she tries to hang herself.
Later, she is describing what happened (possibly to a psychologist) and she says something like “they forced me to hang myself.”
