I have known too many people -- mostly women but also several students of both genders -- who cut themselves . My school never seemed to know how to handle them -- usually by washing bloody items and ignoring it happened -- but I tried responding with compassion . They didn't need someone to judge them or use their self - injury as blackmail . What they are going through is beyond my ken , but not beyond my caring . 
Question: What's a possible reason the people cut themselves ?
Because they have serious psychological issues .
