There is no single answer to this question. There are many factors, such as traumatic and difficult life events, that can contribute to suicide risk. However, an estimated 90% of people who take their own lives have a mental health condition, such as a depressive disorder, bipolar disorder, anxiety disorder, schizophrenia, or substance use disorder. Individuals with depressive disorders are especially at risk for suicide, but this risk is not overwhelming. Most people living with a depressive disorder or other mental illnesses can receive help through awareness, education, and treatment. The most common source of suicide risk is when a mental health condition is mistreated or left untreated.
