Believe the individual. Trust their pain testimony. Involve the individual and their support system. Care for the pain. It is not a secondary symptom.
Time is critical with suicidal individuals.
They are in jeopardy and may be within hours or days of succuming to their condition. Immediately impacting their pain is the only way to save their lives. Suicidality is the state of being suicidal. Secondary prevention - intervention with a particular individual at some point in the suicidal process. Tertiary prevention - intervention with suicide attempters and suicide survivors to lessen risk.
