Actually, depends of my mentality at the time. I had days where I thought death was comforting in a way and others where gets me really terrified. Last thing I would not really to die from is from being assassinated by some stranger in any crime events, being electrocuted, drowning... you know, very painful ways of dying.
If I decide to ctb on my own, I would mostly feel not being scared of death. After all, we're mortal beings and we do not live forever. However, I mostly feel more fearful of death most of the time. When I get depressed, I often think about ctb. Also I get the opposite of being scared of life and I feel that way more intenesly than what death makes me feel but occurs less often. They're just a bunch of "what if..." running through my mind.
I really like to think that when I die one day, I would finally be living happily in peace where I would meet others that I knew throughout my life, my paternal grandfather and my childhood dog again in Heaven (I'm not by any means a Christian) and knowing my pain and suffering is finally over, relieved that I'm in a better place and that my soul will never ever fades away.
