Mental illness refers to a wide range of mental health conditions that affect your mood, behaviour, and thought patterns. Examples of mental illness include depression, anxiety, schizophrenia, and eating disorders. There is no shame in having a mental disorder or in seeking appropriate treatment or help for that disorder. Most mental illnesses don't improve on their own, and if left untreated can get worse over time. If you suspect that you or a loved one may have a mental disorder, please contact your family doctor. For more information please visit Health Canada or the Mayo Clinic.
