Most people with schizophrenia are harmless to others. They’re more likely to hurt themselves than anybody else. Sometimes that includes trying to take their own life. You should take any suicidal talk seriously, and pay attention to poems, notes, or any other things your loved one creates that are about death. Also, be suspicious if they suddenly go from depressed to cheerful. This change could mean they're thinking about suicide. For help on the spot, call your doctor and the National Suicide Prevention Lifeline at 1-800-273-8255.
