It's also entirely possible that life is indeed just messed up in a way that human brains didn't evolve for and can't deal with - all the societal changes, breakdowns of close relationships and communities (e.g. the disappearance of the 3rd place in addition to work and home), as well as most people being stuck in an endless stressful rat race that they will not ever escape due to the state of the economy and the moneyed interests, alongside the daily stress and social media making things worse. All the injustice out there, maladaptive behaviors, normalization of hate and borderline tribal "us vs them" mentality at pretty much every turn (genders, politics, race, everything). Might be a consequence of being too exposed to information out there and not ignorant enough, but go figure.

This isn't new. People have said this for centuries. You can find people wondering this when the steam engine was invented, when the printing press was invented, etc.
