Death frightens me as well. I've thought of shooting myself with a gun, but no matter how instantaneous a gun is, know I will feel pain, even if for a brief moment. Just because it's brief, doesn't mean anything. A brief moment of agony can feel like an eternity, otherwise, why would we feel fear when thinking of shooting ourselves to begin with?
If death could be as simple as laying down in peace, I think a lot of people would be okay with it. But suicide is usually messy, violent and disturbing. People generally are against what is essentially self murder, and the thought of murdering myself, while for me is fine, definitely puts people off.
Even if I live to old age and die of natural causes, I know death will be uncomfortable.
At 38 years old I can definitely say I lived a bad life, one of neglecting my health and not listening to others.
I have to ask if you were serious about CTB, could you at least say you lived a good life or at the very least took care of yourself?
Maybe that fear of death is telling you not to end it all because no matter how bad it gets there is always worth something to live for.
I know that's not always true, but if it was in your case, would that be enough to keep you going, despite the struggle?
