Words can limit potential. People with mental illnesses want to be known for their skills, talents, and abilities, not for their diagnosis or "label." A mental illness, like a physical illness, does not define a person. In addition, terms such as "crazy" or "nuts" reinforce the discrimination and negative attitudes associated with mental illnesses and often keep those who need and want help from seeking treatment.
Focusing on use of language is often the first place to start addressing social exclusion and discrimination against people with mental illnesses.
