The one thing that I will say (in the interest of complete and total honesty) is that after my hospitalization, during which I was very open about the chronicity and severity of my ideation and the extent of my preparatory behavior (as I would have certainly have ended up dead if released from the ER instead of transferred to the bin), is that medical personnel are now far quicker to threaten me with sectioning than they were before.
I was told that I would be sectioned if I did not spend the holidays with family due to concerns about COVID. When asked about intent, everyone makes me look them in the eyes and repeat what I've said when I deny that I am actively planning to kill myself.
The truth is, while I was in the hospital, I used my phone to renew and update the license that I used to procure my method for the express purpose of reordering it. (I had to hand the stuff over as a condition of my release.) Documentation arrived last week, and method is already on its way. That said, crisis intervention didn't work for me, but it might work for you. I think it's worth pursuing. Death is final; you owe it to yourself to investigate the alternatives first. Especially if you have any questions whatsoever regarding whether or not this is truly what you want. Treatment IS effective for many of those struggling with mental health conditions. You might well be one of them. It would be a shame to opt out without giving it a try.
