Check out a couple chat bots with memory. Memory is being stored id database. One is trained to be a psychiatrist and the other a friend bot both novelties and currently free to use. I'm interested to see if either have any value as either a novelty or something real.
Also, it's good to see, given the title of a psychologist/psychiatrist and gpt-3.5-turbo continually reminding the person to get professional help outside the tool and even offer contact numbers. https://www.psych-bot.net and https://www.pal-bot.com
