Well that's definitely one way to look at it, can't say I'd see it so limited like that for no reason but if you die and things really are like that nothing is going to be anything enough to give a shit, so it's weird to just assume as a spirit or something else, you don't continue in existence in some way. Ever used dissociatives? That's pretty much experiencing what it's like not to be. Honestly with the possible truth of it being so grim there doesn't seem much reason to me to just see it that way and then use that attitude to justify my misguided actions on this world. Indeed, they are misguided. I digress. I am a major pessimist because I pretty much can't shake it, I'm fairly certain I am bipolar like my uncle but I don't seek proper treatment for it. If I see your view on things as highly negative, you might wanna take a step back if you want to have any chance of a pleasant life. Maybe you are happy, fuck it I don't know, but your view on death certainly doesn't suggest so.
