NAMI's support and public education efforts are focused on educating America about mental illness, offering resources to those in need, and insisting that mental illness become a high national priority. Mental illness is a serious medical illness that affects one in four families. No one is to blame. Treatment works, but only half of people living with mental illness receive treatment. NAMI has engaged in a variety of activities to create awareness about mental illness and promote the promise of recovery. Free support groups are one of those avenues.
