I absolutely lost all sense of morality. The black pill makes morality ridiculous. Once you know that people get the utmost admiration, love and respect for their aesthetic appearance only, being a moral person just seems like enslaving yourself for society. You're moral and attempt to contribute, society benefits from it only to use all your contribution to chase the evolutionary motive of stronger, faster, bigger. You also learn of the insane discrepancy between what people do, want and like in their deepest fibres and what is best for society. It's a nihilism I haven't come close to encountering in any of the depressing existentialist books. Being blackpilled just makes you realize how even people like Dostoyevsky are deep down optimists who believe in a good humanity.
You start to realize everyone is deep down an asshole, that nothing has any sense whatsoever, that nothing is worth any effort because what you're giving effort for - society - is sick and disgusting.
You learn that 50% of the population lives insanely easy lives but their inherent subhumanity keeps them from coping even with their easy lives. That the entire society brainwashes you into thinking calculating and instinct driven people are the angels on earth bringing flowers and goodness, while they spent 80% of their free time on what's in the end not much more than attempting to be better natural selectors, trying to look as pretty as possible to convince Chad to fuck (impregnate them). Getting insecure over their body issues because Chad (good genes) might not want to reproduce with them. Getting jealous of other girls, fighting with them etc. Having hobbies that just amount to make up and exercise meant to improve attractiveness for Chad. (yoga, make-up, workout, animals). Living in a society where you're forced to worship the proxy of the devil is, indeed, hell on earth.
Being blackpilled is the end. There is no way back, you see too much, you realize too much and you start to understand there's nothing you can do. There is nothing to work for, nothing to live for etc. other than your own entertainment.
Personally I cope pretty well. I take society like an insanely difficult game I cannot win in, but I take pleasure in me becoming better and better at understanding how it works and changing my life to reflect my understanding. I have something to do for myself, at least.
