For your sake, I hope you'll change your view on this eventually. But I appreciate your honesty in expressing your belief that I should just kill myself right now.
It depends hugely on what value you assign to the human mind. If you believe that humans are "just" wildlife and mere existence is the highest achievable goal, you're likely to come to the conclusion that nothing matters but procreation.
But I highly doubt that you really believe this, because you're here, on HN, thinking about and debating matters that are far removed from the static archaic society whose values you ostensibly subscribe to.
There are a lot of people who think that human life is more than a mere bacteria-like existence, and that its value extends beyond our biological goals and limitations. Whether you like it or not, we have long since started to explore problem spaces that could simply never be addressed with mindless biological evolution. For a few thousand years now we are in the process of out-growing our original substrate. As a civilization we're engaged in a complex struggle to eventually grow beyond an existence that is defined only by the most basic biological needs.
If you can find it within yourself to identify with that struggle in some way, you may find that defining procreation as the ultimate end-all-be-all was the most bleak and unproductive premise you could possibly come up with.
