imo, theres no life after death. the purpose of our existence is
merely to populate and crowd the earth and after we breathe our
last - that's it - "bye bye". i think of it as much as you do, and
it does get frustrating at times. i mean, you get furious when you
realize that our existence is that "cheap" and "meaningless". none
of us are "special" as to be freed from death.
but on the other hand, theres still those theories and concepts
about "life after death", with the "ghosts", "reincarnation" and so
on ... but imo, they are most probably mere fantasies we dream up
of to assure and console ourselves. we don't see ghosts of
dinosaurs stormin around, do we?
*not that i don't believe in
ghosts though*
anyway, don't think too much. countless, billions of humans like
us, have died and ceased to exist. you, or i, or someone else may
die in the next second, be it via intentional or unintentional
means. but what's the point in looking into the future and worrying
about it? you can't prevent it anyway.
be happy and fulfill yourself now ^-^
all the best.
