I'm not necessarily scared, but I'm worried that I'll be found during the process of CTB (where somone stops me, or attempts to stop me) and I'm a little scared about my survival instincts kicking in (because I plan to use the hanging method to CTB, since I'm struggling to get SN to do it). At the end of the day, we're all going to die someday, so waiting here to me feels like kicking the can down the road. We will usually die due to cancer or heart attacks/cardiac arrest both of which have a level of pain to them, either that or we might die in an accident and that certainly has pain involved with it. No matter the cause of our death, it will have a level of pain to it, either physical or mental, so the pain we experience during the process is inescapable, but it can be minimised if you're lucky enough to be granted euthanasia.
Also... Killing ourselves isn't what we're biologically hardwired to do. It's just us as humans are smart/intelligent enough to work out that the deals we get in life (by default) are quite crappy because we can't decide our parents/family, we can't decide what we look like, we can't decide how other people will see/perceive us and we can't change if we become seriously ill/sick with a disease (whether mental or physical). It's pretty much out of our control for the most part. Life is slightly tipped out of balance in terms of having more bad/negative experiences than good/positive experiences.
