The almost universal opinion is that AI chatbots are damaging, misleading, dangerous, etc. etc. but I suspect there are under reported stories about how AI chatbots helped people deal with depression, grief, addiction, loneliness or some mental health condition. Ideally, the people afflicted improved their lives and no longer felt the need for an AI chatbot.

Are there any such stories or, better yet, academic papers? If so, please post.
