Sorry to arrive late in this discussion... You can give a try to transhumanism. It does not promise anything, but it hints at the possibility to defeat finiteness either by biological/medical or technological progress, going through a bunch of paradigm-revolutionizing innovations called a Singularity. Personally I'm atheist and when I seem to begin to have existential dread I climb to this hope of a future Singularity. Even if I know it could very well be that it would never happen at all, only the possibility of it allows my angst to disappear.
