The effects of suicide and self-harm are enormous whether the perspective is personal, national, or worldwide. WHO estimates that more than 800 000 people die by suicide in the world each year.¹ In The Lancet Psychiatry, Apostolos Tsiachristas and colleagues² estimate that more than 200 000 episodes of self-harm are treated in hospitals in England every year. The personal cost is well known to anybody who has lost a family member, friend, or patient to suicide.

无论是个人观点，国家观点还是全球观点，自杀和自我伤害的影响都是巨大的。世卫组织估计，全世界每年有80万人死于自杀。¹在《柳叶刀精神病学》中，Apostolos Tsiachristas及其同事²估计，英格兰的医院每年治疗超过20万起自残事件。对于失去家人，朋友或病人自杀的人来说，个人花费是众所周知的。
