I'd take it a step further and ask why we always consider depression, anxiety, drug abuse, etc. as an individual's "mental illness", when many of these illnesses seem to be inexorably linked to the broader societal sicknesses we find ourselves living under. Economics, politics, technology, cultural norms, community (or lack thereof), health and wellness; all of these things are directly or indirectly affecting the mental health of the population at large. Even if we double down on mental health treatment for individuals, it is ignoring the larger, more complicated issues that are likely at the root (of at least a significant contributor) of these problems. And yes, I think it is a perfectly valid choice for someone to check out if that's what they want to do. Mental health or whatever aside, if you don't want to live anymore, for WHATEVER reason, I don't see why anybody else has the right to try to stop you.
