What is it about death that scares you? Is it the 'before' - as in executing the method, how it's going to feel, struggling alone? Is it the 'during' - as in the moment of death, how it might feel, will you be conscious of the 'moment', will it be black and white (suddenly goes black) or more like day and night (gradually fading to darkness). Or is it the 'after' - what about family, what about consequences of an afterlife, what does it 'feel' like to be dead? Etc.
For me, it's the after that troubles me. I can't quite wrap my head around the idea that once I do go, all of my thoughts, feelings, hopes and dreams - even those long extinguished will cease to exist, and from my personal perspective it will be like rewinding time as if I'd never been born.
It's something I'm working on though, I've been debating whether to do a 'simulated' death where I basically go through the motions of my plan but without the actual suicide element and knock myself out for a few days with some strong meds so when I wake up I'll have an idea of what it felt like to slip away.
The other important thing for me is the moments right before death. I don't want to have a near death experience that's negative, so I'm considering using a hallucinogen to design a positive, spiritual experience for myself right before I die so my final moments will feel like visiting the afterlife - even if no such place really exists.
Anyway, sorry for going on - can relate to you all.
