I personally would still choose SN over hanging. I'm not an SN cheerleader, I've criticized it, I don't buy into it being peaceful, nor do I buy into the thread you're referencing, and I was vocal about it there and will leave it there, not drag it over here. But I've researched the heck out of the method, journaled about it, even accidentally got a little bit of it in my system when I blood tested (had to drink a lot of water, I do NOT recommended playing around with it). Therefore I know some symptoms I'll experience that I'll have difficulty with, and I have made/am currently making more provisions to lessen them if I decide to go that route.
I've tried partial hanging many times, in a variety of positions, it's too intense. If there were terrorists at my door, I would overcome the SI because there would be a greater threat, therefore hanging would become survival. But there's no such threat, and I'm not desperate enough to go through the torture of even full suspension hanging. Desperation can do much to overcome SI, I think.
I'd advise if you're feeling fear to step back, do some self-care, and let it pass, then revisit that thread. Fear is a powerful motivator, but it can also override critical thinking.
