Abstract
Mental health support over multi-turn conversations stresses LLM reasoning, empathy, and safety in distinct ways. We systematically examine the limits of reasoning-focused LLMs in multi-turn mental health conversations, isolating failure modes that pure reasoning cannot address, and discuss design implications for responsible deployment.
