Reframe that first sentence. Since everyone is unique -- down to their genetic DNA -- you aren't missing anything anyone else has -- maybe companionship? But you have your own unique gifts and talents and insights to contribute to this world should you choose to. Right? You have something to offer!

If you want to be part of a group, because you feel lonely or isolated, that I can empathize with. Then, it makes sense to say that you feel are you missing something others have -- camaraderie. We all need camaraderie in our lives, no matter who we are or what we believe.

To be alone is to suffer. I've always had a hard time staying with a social group. I don't know why, but I don't suffer fools well, and I hate cliques. So, I'm not good with social cliques. I have been alone for about a decade and have fringe acquaintances that I contact when my loneliness reaches unbearable levels. Otherwise, I'm alone ALL THE TIME and have adjusted to it. It's bizarre. But that's how my life turned out.

I think your fears of death and poverty are shared by 99% of the population on earth. Including myself.

I do agree with your opinion that people should abstain from having more babies. At this point, the human species has overpopulated the planet ten-fold, and continues to desecrate the natural world to our own downfall. Oceans of plastic, non-existent rainforests, wildlife starving to death b/c humans have destroyed their food sources and ecosystems. Humans are a plague on the earth. But I digress...

That is to say; sounds like you found your philosophy with anti-natalism. I encourage you to read up on Absurdism. Also, a fun book I recommend reading, "Confederacy of Dunces." Ignatius Reilly will inspire you. That's one of my FAVORITE books with a protagonist who is definitely an absurdist.
