Yes, the fear of pain is one of the reasons why I haven't killed myself yet. I would rather be unconscious in the hours or minutes leading up to my death so I can die as
painlessly as possible. As others have already mentioned, I'm also afraid of the pain which might occur (physical or otherwise) if my attempt doesn't succeed.
And that's pretty depressing, because if I really wanted to kill myself, I would already have done so regardless of the pain, but here I am, pining after death....yet another example of the fakery of my existence. It's all meaningless in the end. Nothing is real, myself least of all.
