If doctors and experts in the field don't fully understand it, then certainly nobody on BITOG can fully understand it. Saying you or anyone else doesn't fully understand it because of obvious things they say isn't making it "personal" ... it's simply point out a fact that they don't fully grasp it. That's no different than someone not fully grasping lubrication and tribology, or fully grasping the way oil filter and an oiling system operate, and someone pointing out that they don't fully understand it because of some comments they made about the subject matter that showed they didn't grasp the subject matter. If you want to take it as being "personal", then go for it.Apparently it's doctors who don't really understand the illness, nor the cure. If they did we would not have the tens of thousands of annual suicides (most arguably due to depression), and the 60 thousand drug addict deaths annually from overdoses (large % of drug addicts started or stay on due to depression)...
So it sorta is personal attack on me, when you continually say that I don't understand, when nobody apparently really does understand the cause or cure. Saying the cause could be effectively anything, is really not particularly helpful.
There "drug" solution is part of the big-pharma problem. For the truly hopeless, poor, destitute, victims, homeless, suicide is easier to understand. How is a rich/powerful/famous person hopeless and fatigued? They have the power to alter their environment drastically.
It's a very narrow viewpoint to believe that people who have everything in the world (money, success, fame, good physical health, etc) should never feel depressed, or never get so depressed that they take their own life, simply doesn't have much knowledge on the illness. People who view depression that way can not judge or make conclusions about how someone behaves from it just based on how they might react/behave if they were that same person. That is the recurring viewpoint you seem to give - you just can't understand how someone with so many good things in their life could do such a thing ... but it happens all the time. In extreme cases that lead to suicide, nothing matters includeing money, success, fame, etc, etc. When depression gets to that level it is totally over-riding everything else in life.
Yes, the cause of depression can be caused by many things ... it can simply be a chemical imbalance in the brain (synapses not working properly), and not necessarily caused or triggered by some kind of life event. This is why many people who seem to have everything can still suffer from extreme depression. That's the part it seems that you don't understand, and why it's so puzzling to you why anyone would take thier own life because of extreme depression when in your mind they "have it all" and there should be no reason. You nor anyone else can be the judge on how depression should effect anyone, or how they should react to it ... nobody can, expect the person it's happening to. That's what makes it so difficult to diagnose and treat. Many people don't seek any help because of the negative stigma of depression, and that's the worst thing they can do.
