being bi-polar is tortuous at times. Learn about it and have some empathy. Try going days without sleep then not being able to get out of bed for days.
There is a lower number of suicides amongst Catholics, which I attribute to the fear of hell since suicide is a sin. So there would be a percentage of people who would continue to fight the chemical reaction in their brains. Getting help is possible, too, but with some, getting out the door is difficult. Plus there is the possibility of multiple issues in addition to depression.
Like having an ache in your lower back. Why? How many things can cause that?
What do you want? Do you want people to commit suicide, or don't you? People commit suicide when their valuation of death tilts away from their valuation of life. If you see a man standing on a ledge, about to jump to his death, what do you tell him? Do you commisserate with him; tell him you understand perfectly what he's going through, and that he's powerless to act otherwise? Or do you attempt to tilt his values back toward life by pointing out that he has responsibilities both to himself and to the others who love and depend on him? Do you sympathize with his hopelessness and despair, or point out that in refraining from his intended act he clears the way for the possibility of brighter days to come; days he'll never experience if he makes the fatal leap? Do you appeal to his sense of responsibility; of manhood (if he's a man), or do you extol the virtues of cowardice and surrender?
Suicide nowadays is being treated exactly like unwed pregnancy. When the latter was stigmatized, we had very little of it; when empathy and understanding became the order of the day it became an epidemic. Ditto with drug abuse; with alcoholism; and almost any other vice you'd care to name. It's a sign of the sickness of our times.
