Exactly. Most people seem unable to comprehend that you could have depression when "you've got it made." You see it often enough in the music industry (Chester Bennington, Chris Cornell, Kurt Cobain for starters) - people that are very successful in their careers, had people close to them that cared about them, but that doesn't "solve" depression.

On a personal level, I am fairly successful in my career, have financial stability and the ability to take vacations, and am married to a wonderful woman. My depression isn't nearly as bad now as when I was a teenager, but it's not like I'm just fine now. Sometimes a random thing (work stresses, physical pains, etc.) will cause my depression to spike, making it significantly harder to want to do anything. It makes my with suffer, my relationship with my wife, I'll slide in doing exercises, and don't get enough sun... All of which just make the depression spiral. Fortunately after a bit of that, either I find something to kick me back into "correcting" mode or my wife pushes me into healthier habits (like going out for walks) to get me back to at least "manageable." All of that to say that people with depression can ebb and flow regardless of how "good" their life is, especially when viewed from the outside. And sometimes the inability to be happy when you "should be happy" just make it worse.
