> If you're someone I know well enough to judge the credibility of a plan to kill yourself (which could mean "complete stranger" is the plan is particularly credible), and I become aware of such a plan, I would feel obligated to ensure you saw a doctor, with the word "ensure" chosen carefully.

The scenario I am describing to you is one in which I was seeing a doctor, regularly (once a week). I was already getting help. The only assistance I was not getting was inpatient, take-your-rights-away-for-a-while forceable assistance.
