Barriers to Seeking Help

Top reasons people don't see a professional

Key finding: According to NIMH, only ~half of people with mental illness in the US receive treatment. Globally, WHO's 2024 report found over 1 billion people live with a mental disorder, yet most remain underserved. In low-income countries, the untreated rate can exceed 85%. The COVID-19 pandemic added an estimated 53M new depression cases and 76M new anxiety cases in 2020 alone — most of whom never saw a professional.
