What if you could spend it with cats? What if it didn't have to be forever - if you could end it any time you chose, like after 1000 years or whenever? It seems what you don't want is only a very specific version of an afterlife.

Does any major belief system actually have an afterlife in which you can _die again_?

I suppose various types of reincarnations might be that. Or afterlife is just temporary state in between. I suppose reincarnating just to die again is something in some belief systems. Sometimes with goal of being liberated from the cycle.
