Suicide is the act of intentionally causing one's own death. Mental disorders, including depression, bipolar disorder, schizophrenia, personality disorders, and substance abuse—including alcoholism and the use of benzodiazepines—are risk factors.
It is common to feel guilty: that you ‘could have done more’. People may feel they should have picked up the warning signs, or blame themselves for things they did or didn’t do in the period leading up to the suicide. Many feel anger and betrayal. These are common and normal reactions.
