My existential aloneness realization had a lot of stuff going into it. A lot of history and prominent recent experiences with unrequited attraction, with being misunderstood, and with people just choosing to not build connection and seemingly not seeing the value of it or just how much richer it could be. The emotions I felt from that catalyzed it. Thinking about it set it in motion.
Also, I was under the effects of a drug at the time which disabled a lot of my habitualized cognition. So my cognition was flowing in a very "raw" way. And I was exploring where that would take me, instead of trying to fight it by conscious effort to maintain careful rigorous thought or emotional and mental state from which I could reliably act and maintain appearances.
But the thing that really hit me was when I realized the much bigger and more fundamental problem: we are all isolated in our own experience stream. There is only ever inferred knowledge of other minds. We never truly know each other, we can never truly perceive each other directly. We can't. It is a fundamental limitation of how reality works - of how any sensical reality can work. It is the curse of being a mind - to be permanently separated from any other possible mind by this divide of inference. We touch other minds at best as if through gloves, but really in many ways we do not touch at all, we just see each other on the screen of our experiences. That screen, if you look at it just right, if you stop looking through it and just look at it, is cold and lifeless in comparison to the warmth we can conceive of on the other end.
I wept when that hit me, more intensely than I ever have, at least since I was a fairly small child. Alone! Oh god we're so alone! We're all so utterly and completely alone! Trapped forever in an existential fishbowl by ourselves, every mind in its own isolated bubble of experiences!
I rebounded quickly, of course. I cope well, and I cope fast. I quickly made peace with the fact that we interact through an impenetrable experience condom. I found comfort in the reasoning that an iteratively inferred fuzzy approximation of likely understanding implies actual understanding. I accept that the most connected we can be is by forgetting and not noticing the glass separating us. But it's there. And if you deeply care about connection and understanding of minds, then it is horrifying and devastating the first time you really see it.
