I can understand why someoone would want to sui because I have ideations myself. What I do to protect myself is eliminate things from my house that I would potentially use. For example, I refuse to own a gun. Years ago, I read this book all about sui and ironically that kept me from doing it because it mentions all of the things that can go wrong. When I think about it, I don't want to experience any more pain than I already have, so I don't do it. For me, and this is only my opinion, is that people consider sui when the amount of pain and struggle exceeds their coping resources. And yes, those who don't understand are lucky that they don't. Depression sucks.
