This is very true, and they indeed have won (just not what the world thinks) as they have overcome their SI, no longer have to deal with problems of the living, and have died on their own terms.
I feel similar as well, the only difference is that I still live with family which makes having privacy difficult. I really miss the times where I lived independently or at least without having someone present at all times.
Well said. Sometimes life just sucks in general and regardless of how much "success" one has, the feeling of existential dread and eventual end will always loom around. I believe one of the founders of TRTNLE (The Right To No Longer Exist) once stated that all humans are already dying from the start of time.
