Suicide is the act of intentionally ending your life.There is no single reason why someone may try to take their own life but certain things can increase how vulnerable a person is to suicidal thinking and behaviour. Most people who choose to end their lives do so for complex reasons. Certain factors are known to be associated with increased risk of suicide. These include drug and alcohol misuse, history of trauma or abuse, unemployment, social isolation, poverty, poor social conditions, imprisonment, violence and family breakdown. In many cases, suicide is also linked to feelings of hopelessness and worthlessness. In addition to these, a stressful event may push a person ‘over the edge’, leading to suicidal thinking and behaviour.
