Exactly why people turn to AI, which I think is good enough for "casual" mental health advice (the kind people can do themselves by reading self-help books or talking with empathic friends). Arguably it's safer than talking to strangers online because now that they've been doing it for a few years, they will (or should) have plenty of safeguards, unlike people on the internet who can talk out of their ass (like me!) and give bad advice. In theory the LLM will escalate or recommend professional help if they're out of their depth.
