Where it is allowed its usually for those who are at end of life care and are making the choice to go out on their own terms. The issue with suicide is how do you decide who has tried hard enough? 

For instance, i have CPTSD and was in that mindset from 6years old to 25. Im 32 now and only just starting to feel real joy and contentment. Even now, im pretty indifferent to death but no longer actively seeking it. At lot of the time people are depressed because of situations they cant control (most of which can be fixed with money)

But i do aggree that people should never be talked away from suicide, not because they shouod do it, but because it never works. Its often a last ditch effort at maintaining control when other efforts have failed.

There are many kinds of depression 

There’s two large general group they can fall into. 

1. You are depressed because no one loves you. Your life sucks. You don’t have friends. You hate your job. You have no money. (This is the one where most of the issues can be fixed)

2. You are depressed. You have love and support of your friends and family. You are financially stable. You could quit your job tomorrow and still retire comfortably. Yet, there is nothing you want. You don’t want to die. But you don’t want to live either. Nothing has a point. Nothing as meaning. These are the ones who end up attempting suicide in the end. Like the guy in this post. 

First one is external factor depression.
