Yeah like others said, even if assisted suicide becomes a thing, then depression isn't enough to be granted. It's only if you're physically dying and there's no treatment or cure. I still think the small progress we're making with assisted suicide is great, but it has go a lot further than that. Everyone should be allowed assisted suicide, no questions asked.
I also think they need more/better assisted suicide methods, because not everyone feels comfortable with the current method they've opted for. Just like in this forum, most people have strong preferences about which CTB method they want to use, and they simply can't imagine themselves using some of the methods. Some people want to leave their corpse behind in a beautiful condition at the cost of suffering during CTB, while some think that's unacceptable and would much rather explode their head with a shotgun to reduce suffering as much as possible.
So, assisted suicide still has a long long way to go unfortunately.
