I don't believe in life after death. I enjoy occasionally reading about some of the idealist's perspectives regarding consciousness as fundamental, but even they generally don't go as far as to suggest the continuation of an individual, ego-based consciousness after death.
In truth, I've suffered from existential dread for most of my life. It was crippling for a few years, but even now I am tormented by it. Literally just last night, I awoke suddenly with a racing heartbeat from the realization that I will cease to exist in the near future.
It's brutally gay, but I really just cannot tolerate the thought of eternal nothingness, my consciousness suddenly extinguishing, and the finality of it all. If I could delude myself with religion, I would. I've not lived a risk-averse life, and that surely hasn't helped, but when I'm at home and have too much time on my hands, it's even worse.
