Yeah I expect to die alone. I've had some romantic partners in the past, no kids, and one sibling with which I am on good terms with, but not particularly close. But by the time I die, it's very likely I'll have no one save for maybe a long distance friend or two.

Given the state of the world, I expect that if I am lucky/unlucky enough to reach my elder years (currently I am middle aged), I will experience worsening conditions as climate change and political turmoil makes resources more scarce and I become increasingly more feeble as my body and mind succumb to whatever fate has in store for me.

Long of the short of it is I don't expect my death to be quiet or peaceful. Whether somebody is there or not at the end doesn't really concern me. My legacy definitely doesn't concern me.

That said, I'm sad that it's likely I will have contributed jack shit to making this world a better place by the time I die (quite the opposite actually), and if there is a Hell, I won't be surprised that's where I'm going.
