I'm scared to death (excuse the pun) of the idea of not existing. I don't care how hard my life is or how much pain I'm in... Knowing I'm alive, and real, and exist is really something I don't want to give up on.
Although, I guess that's what makes life so beautiful. It IS a ticking time bomb, it will end, and that will be it. After all, there won't be anything. It's be like it was before you were born... nothingness and nonexistance.
I also hate the idea of being buring... six feet under... I plan on being cremated. 0.o
Although according to that deathclock site, I won't be dying until June 1st, 2091. YIPPIE!
