What You Can Do if You Suspect Someone is Suicidal
Ask him or her! That may sound absurd and very scary, but you must ask him/her if they ever feel so bad that they think of suicide. Don’t worry about planting the idea in someone’s head. Suicidal thoughts are common with depressive illnesses, although not all people have them. If a person has been thinking of suicide, he or she will be relieved and grateful that you were willing to be so open and nonjudgemental. It shows a person you truly care and take him/her seriously.
If you get a yes to your question, question the individual further. Ask if he/she has a plan, or a method, or if they have decided when they will do it. This will give you an idea if they are in immediate danger. If you feel he/she is, do not leave them alone! The person must see a doctor or psychiatrist immediately. You may have to take them to the nearest hospital emergency room.
Always take a suicide threat seriously and never keep it a secret!

You must never call a person’s bluff, or try to minimise their problems by telling them they have everything to live for or how hurt their family would be. This will only increase their guilt and feelings of hopelessness. He/she needs to be reassured that there is help, that what they are feeling is treatable, and that their suicidal feelings are temporary.
If you feel the person isn’t in immediate danger, you can say things like, “I can tell you’re really hurting”, and “I care about you and will do my best to help you.” And follow through – help them find a doctor or a mental health professional. Be by their side when they make that first phone call, or go along with him/her to their first appointment. A supportive person can mean so much to someone who’s in pain. This is an opportunity to interrupt the long process that for many, leads to suicide. You may save a life!
