Suicide is defined as purposely ending one's own life. Common methods include bleeding, drowning, hanging, jumping from heights, explosions, firearms, poisoning, vehicular impact, and electrocution. Mental illnesses like depression and mood disorders, stress, substance abuse, unemployment, loss of self-esteem or reputation, economic debt, anxiety, and frustration can cause suicidal thoughts. Additional risk factors include a personal or family history of suicide attempts, physical or sexual abuse, social rejection, grief, domestic violence, harassment, chronic illness, and torture.
