I'm just tired

I'm sure that many are feeling the same way. Existential fatigue hits hard while trying to achieve the impossible. For people looking for the answer or enlightenment or whatever it is. That unreachable explanation that explains everything. As I've tried to reach this, I've noticed that my brain is just overloaded by the relations of information I'm trying to calculate into an explanation of what the fuck this is.

Each new understanding increases the load of relations, which has to be processes by the brain. Brain is a very optimal organ, it packages related and unrelated information into a web of concepts , which eases the load of simultaneous calculations. You don't have to calculate all the math of existing object in space to understand that it is what it is. You rely on concepts you've built, which are basically automatic processes requiring minimal effort. However the amount of information available increases with every moment and our brains tries to optimize those, but no matter how optimized your process of being is, the load for the brain to process increases with every passing moment.
