Mental health pressures are reaching millions, but the gaps in access and outcomes are where the real story lives. In the United States, 9.5% of adults reported a serious mental illness in 2022 and 5.8% still had an unmet need for treatment, while 48.0% of adults with any mental illness received counseling or therapy in the past year. Add in worldwide impact like 700,000 deaths by suicide each year and shifting use of digital tools and therapies, and you get a picture that is both sobering and uneven.
