May is Mental Health Awareness Month. Mental Health Awareness was started in 1949 by the Mental Health America organization (then the National Association for Mental Health). Every May since then, Mental Health America selects a theme and releases a "toolkit" meant to guide organizations in their outreach programs.
The purpose of Mental Health Awareness Month is to raise public awareness and education about mental illnesses, reduce negative stigmas surrounding mental illness, and draw attention to suicide, which can be a result of some mental illnesses. Following the lead of Mental Health America, many other organizations now run campaigns through May related to mental health awareness,.
