This isn't telling depressed people "everything is happy rainbows" It recognizes that depression is shitty and makes people feel worthless, even though they aren't.

Depression isn't necessarily "the world [being] shitty in ways that make people who are predisposed to feeling like shit for no good reason feel even worse." I know people who have pretty decent lives by pretty much any external measure you can imagine, and they're still depressed. Some of them are hanging on because they know people would miss them if they died.

So, no, don't tell people who feel like "everything is worthless and [they] have nothing to lose" that everything is awesome, even if it looks like it. But, this article isn't doing that. It's about someone who was loved, who is missed and who died from a terrible illness.
