People sometimes kill themselves.

Others are judgmental about it.  Some say if they want to do it they should go ahead and do it and get out of everyone's hair with their self-pity.  Others say it's a sin against God.  Even others say it's caused by demon possession.  Finally, and this is probably most common, there are those who say the suicide had to be insane to do such a thing.

There are many reasons people do this, and a lot depends on the culture.  The Roman aristocrat who fell on his sword rather than be executed in one of the brutal ways Romans tended to execute people was doing the honorable thing.  Many societies see some suicides as honorable.

Most of us can imagine a scenario where we would kill ourselves -- incurable disease combined with unremitting nausea would do it to me (pain I can handle better).  Probably also a disease that promised in the future to render me helpless and a burden.  We all die someday and some things are worse than death.

However, suicides today most often are associated with the set of diseases put together as "depression."  Those who have never experienced it have to remember that this is not "being sad."  It is another thing entirely.  It is a cloud of blackness that pushes you down and doesn't let you think at all clearly but only makes the world hopeless with no escape.

One thing to remember is that depression is not insanity in the usual sense.  It is a mental illness, but not one that involves irrationality (I sometimes think it is a case of being too rational).

Psychiatry has tried all sorts of ideas on how to deal with this, and often can have a temporary effect, at least until the depression passes, but then they lose the patient next time around as the disease figures out the psychiatrists tricks (not unlike the cancer evolving resistance to the treatment).

It is true that how we look at the world is a great part of the problem -- the old "glass half empty or half full" sort of thing, but knowing this does a depressed person little good.  Truth is, one can always think up the negative side of things, as the world is not all that good to people and most young people have their ambitions squashed fairly fast anyway.

It is purposeless to try to find a purpose in life.  The vast majority of us have only one purpose in our existence -- to give life and happiness to our children.  This is something of an evolutionary trick, since usually the children don't turn out as expected and sometimes turn on us, and we have to adapt.

In the end the only real treatment for depression is going to be medical, not psychiatric (psychiatry is seen as a branch of medicine, but its methods and training are different).  The widespread bias against dealing with emotional problems with pills needs to be overcome -- diseases are best treated with pills, although in some cases other forms of intervention can work.

There is no guilt associated with being depressed -- the tendency runs in families and is just part of the baggage we are born with.  It is useless (and in my opinion evil) to tell the depressed to get over it and stop being so self-involved.

Finally, there is no guilt associated with someone who has actually committed suicide.  They should be treated as anyone else who has died of a chronic disease.  The death should be reported as such (not covered over -- society needs to know the reality) but without blame or shame or as a scandal.
