Story I feel like I am not a full human

[Asgard]

I am wracked with the feeling that I was born as some other entity than human. I am an observer, perhaps. I don't actually believe in the supernatural. But a demon or some other supernatural entity that is beyond human understanding or motivation seems to fit the bill. My general mood, my overarching sensation of existing is profoundly inhuman- I feel like something is either missing inside me, or I am missing out on something everyone else has, or some combination of the two.

It's like I don't belong on Earth. I belong somewhere else, or in some other state of existence, or some other society based on completely different psychology and motivations. I'm just so unbelievably wracked with disillusionment. I feel like the whole world is either a lie or a sick joke. It's a big competition where everyone's trying to f**k everybody else. And I hate it all. I wish I could end the Earth- its like an experiment that the scientist feels pity for because it was created with an awful existence that it has no effective means of ending. It slithers across the laboratory floor, writhing in pain and pleasure and mindless impulses, and it won't go away.

 

[Asgard]

Approximately two thousand years BCH, the Tribe's robotic creations rebelled against their creators, in an act of mutually assured destruction. The attack caught the population off guard, with many at work or enjoying leisurely activities. Evidence of people going about their lives is still visible on the remains millennia later. However, prior to the apocalypse, five individuals started seeing visions of strange people warning them of the upcoming cataclysm. The five worked hard to recreate the lost organic memory transfer technology, and built a ship in orbit to carry their experiments. After their deaths, the five were resurrected on this ship, and opted to follow the Tribe's original course back to Kobol, leaving Earth behind.

Sounds like you're alienated from society, as many of us are thanks to widespread access to the internet.
Much of my generation (Gen Z) and eventually Gen Alpha are alienated.
Read Osamu Dazai's No Longer Human, it's a good book about an alienated man. It's an I-novel, basically just a retelling, more dramatic take on Dazai's life. It's one of my favourite novels ever, alongside Battle Royale. (Both of which are Japanese, funnily enough.)
