Why do you think people have suicidal thoughts? Is it reasonable to result to potentially killing oneself to be able to remove the pain a person is suffering from? What are your thoughts about this matter, is it acceptable or not? Why does a person result to thinking of suicide? How can you help the person to change His/Her mind?
Suicidal thoughts come from low self esteem and weak character. That's come at a point in your life where you think you lost everything and that there is no way out of the dark suranding their soul, but that's not true there is always a light at the end of the tunnel called life only if you believe in it and don't let the world crush you. Some people find the answer in faith others in a purpose. Everyone is different. You can help such people by indicating depression and help them with your presence.
