I'm in my 40s, married, and had a fairly typical life, but have depressive episodes from time to time. I have watched over the years as everybody is hunky dory about whatever their fate maybe. That is to say it seems normal that people just accept they might die a tragic painful death from cancer, and get right on with enjoying their candy bar or what ever. I would go as far as to say, that most people are okay to experience mostly suffering as long as there are a few good bits here or there. 

And people HATE to talk about this stuff. It's why being depressed is so hard, the things you naturally tend to talk about drive everybody away. So you put on that mask and talk about football or whatever. 

And I guess I get it. If the first thing people did when they learned they were going to die was end their lives, there wouldn't be much going on in the world. The trouble it seems for those of us who are depressed, is that we aren't wired up in such a way as to be able to ignore this stuff.   

This seems to be depression in a nutshell. That is to say that people with depression tend to just be making realistic observations.
