During a significant portion of the past month, Abby had talked to herself out loud and told her roommate that she had heard voices telling her to harm herself. Her roommate reported that Abby had told her that she occasionally stated that she was Joan of Arc and that the school mascot was stalking her. Her roommate asked to change rooms, and now that Abby was living alone, she did not appear to have bathed in more than a week. This was not typical behavior for Abby, as she had been known to be meticulous with her appearance and hygiene. The roommate expressed her concern for Abby and stated that although she had noticed some of these behaviors since she first met Abby more than 6 months ago, the behaviors seem to have increased over the past month. Which DSM-5 disorder label might match her symptoms?
