The idea that you can fight implies that you should fight, and it also implies that if you “lose your battle,” well, shit, perhaps you didn’t quite fight hard enough. Again, it’s a narrative that mirrors the way we approach other terrifying illnesses. It’s why we read so much into the stories of people like, say, Lance Armstrong (before his fall from grace) — we love the idea that you can refuse to be defeated, that you can prove indomitable. But depression isn’t something you can conquer if you’re plucky enough. Merit is irrelevant here.
