The risk of suicide varies from person to person. However, there are certain risk factors that can make a person more likely to attempt or succeed in suicide. Some of these include a history of mental illness, substance abuse, previous suicide attempts, a family history of suicide, and feelings of hopelessness. Additionally, people who are experiencing a major life stressor, such as the loss of a job or a relationship, may be at increased risk for suicide. If you or someone you know is exhibiting any of these risk factors, it is important to seek professional help.
