For me, I would say that my fear of death is greater than how painful life is for me.

I want to live as long as possible and I even place hopes in modern science to enhance my lifespan well beyond the current average because I'm scared of dying.

I fear being among the billions of other people who are dead and nobody cares about or remembers. I fear being considered insignificant and invalid by other people.

I also fear what is beyond death if there is even any life after death. If there is a such thing as a hell or if reincarnation is real and people who have done bad things in their life get reincarnated into worse lives, than I know that I'm going to hell or being reincarnated into some random peasant in the dark ages or something because I've done some pretty bad things just to try to survive. If there is no afterlife than the fear of not existing anymore almost as terrifying to me.
