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. 

Second one is internal factor.

The two arent mutually exclusive though, chronic depression can be and be worsed by external events.  For me changing my external environment has helped trememdously but im not cured. I still have to take my meds or i will end up back in that mindset rather quickly. 

The point i was making is that you cant judge who gets to choose to end it and who doesnt when it comes to a manageable condition.
