People who really want to kill themseves are beyond help. Fortunately, this is not the case. Suicidal impulses may be intense but short-lived. The majority of individuals who are suicidal even for extended periods recover. All can benefit from treatment.
Suicide is a purely personal decision.
It is a misconception because suicide always affects others. The dismissal is unfair to those who are struggling with suicidal impulses and need help in choosing to live. Asking about suicide can put the idea in someone's mind. The idea of suicide does not originate this way. Suicidal individuals are engaged in a private struggle with thoughts of death.
