I respect OP a lot after he managed to do long drop hanging in public in front of other people. People screamed to him to not do it. His actions were so fast, that noone was even able to pull their phones in time to record the event, though the aftermath was recorded.
This guy had enough courage, and maybe apathy and nihilism like he said, to do what is arguably undoable for most people, no matter how desperately suicidal they are. He certainly has "skin in the game" to talk about fighting SI, as he showed that he is fully able to do it.
About a year after OP's CTB,
@TraveCuda paid tribute to him publicly right before CTBIng also in public, but with SN.
An interesting fact is that OP knew that SN existed and had access to it if he wanted, but still chose to use long drop hanging instead.
Before, he even had recorded
@StrawberryPanic attempt which, for some unkown reason, took a full 40 minutes for her to lose counsciousness after drinking SN, despite the fact that she was still successfull.
People often notice that his Twitter account was full of what could be called warning signs of depression, or even perhaps calls for help, which almost always got completely ignored by everyone. He even wrote that he felt like he was talking to himself there. History repeats itself, it seems: other people only "care" after you're dead, or maybe when you're very beautiful, or when you're at the "very end of the road" and about to kill yourself (whicn can sound like a "Don't do it, just take a pill and go back to work" type of reaction from people).
With that said, though, I think unfortunately his advice about using a "apathic and nihilistic" mindset to fight SI probably requires a lot of control over one's mind, awareness and and counciousness.
I don't see myself being able to use it and I'll stick with benzodiazepines, which have been shown to be very effective against SI. Under the effect high enough doses of benzos, we simply do not care about anything, and it gets so much easier to "pull the trigger".
But I recognize that, for people who don't have access to them, or are into things like self-hypnosis, philosophy, meditation, or otherwise have the neuroplasticity and discipline required to train one's own mind to be apathic and stop caring, this method does sound good to me, and I'd definitely give it a try if it wans't for the fact that I already have benzos.
I was reading the following thread about using benzos to fight SI and it really resonates with my personal experience with them:

And for those who are curious, yes OP did it (trigger warning, disturbing images of hanging aftermath on the spoiler below, do not click it or your trauma may get triggered).
