Is there a way to feel the choking agony of drowning without dying? Please offer your suggestions?

I am NOT a masochist. I just feel sorry for victims of drowning thus, I want to inflict this form of harm upon myself. I sympathize with all innocent human beings who have lost their lives. I have always felt depressed about being incapable of doing anything to save these people.
