There are cases where psychiatric admission is the right call though. Sometimes it's literally life saving. Depression isn't static - it goes up and down, goes loud, goes silent. When you're deep in a life crisis, when you're feeling like you're losing your fucking mind and are actually about to kill yourself those are the places to go to get you over those critical days or weeks to recalibrate and reconsider. I've personally spoken to many patients who were completely releived afterwards and glad that there was such a place for them. If the alternative is a lost life, psychiatry is a valid attempt to get better, even if it doesn't work for everyone.

Of course it's an even better route to get there by admitting oneself - I just believe the likelihood of that happening depends a lot on how afraid people are of psychiatric clinics. And they do vary of course. I personally still would go though. Before I end my life I guess there wouldn't be anything to lose anyway.
