I can imagine that many people who are about to attempt spend their last moments hoping that the method will work and hoping for whatever they want there to be after death. I very strongly believe that we just cease existing after this and I know that if I managed to reach the point where I'm going through with a plan that I feel confident in then I will just be wishing for nothingness in my last moments, I see beauty in being able to sleep forever with this existence not even being a distant memory.
