A survey of more than 5,500 U.S. students found that over 80% use AI, and those turning to chatbots for companionship or support during emotional distress reported worse mental-health outcomes, including more suicidal thoughts and attempts; the findings show associations, not causation. In an England survey, 2.7% of students used general-purpose AI for mental-health support: more than half who rated the experience found it helpful, but nearly two-thirds wanted additional help.
