But despair is only part of depression. Yes, despair and hopelessness is part of it. So is emptiness. So is the inability to feel happiness. So is the inability to enjoy things you use to enjoy, or remember things you enjoy doing. So is guilt, and regret, and self-hatred.
So is being unable to sleep, or sleeping too much. Being unable to make yourself eat, or eating too much. So is not being able to remember what you're doing, and struggling to not hate yourself for it. So is not understanding what's going on around you.
So is collapsing in bed and not leaving, because you're just empty, its not even hopelessness and despair anymore. It's not sadness anymore. It's emptiness. It's a lack of everything.
Yes, words matter. Being accurate does too. And not letting people stigmatize people for having mental illnesses matters. And actually facing that most people on the autistic spectrum end up with comorbid psychiatric disorders, and helping each other with them.
Words matter. People hurt each other with words. People build each other up with words. People take ideas and say "because of this, you clearly aren't good enough".
But it doesn't matter if you call it "autism", or "purple elephants", people are treated poorly, and it doesn't matter if you call it "depression" or "despair", people are stigmatized.
People hurt, and struggle, and deal with this. It's not reducing people to conditions. It's actually taking them seriously. Because the stigma is happening either way. It needs fought either way. Just changing the word doesn't stop it.
In this case changing the word makes it inaccurate too.
