I suppose it really depends on why I’m the last person on earth. If it was nuclear fallout, I’d probably be dead pretty quick.

If we’re under the assumption that everybody just poofed away and I’m the last person, absolutely a few months minimum. I’m within easy walking distance of some stores that have plethora of canned and preserved foods and liquids. I also know some places that already have full solar infrastructure already integrated.

All that being said, I’d probably off myself. I’m fairly non-social to begin with but I’d still be unhappy never being able to communicate with anyone ever again on top of major resource struggles in the future. Never find a partner, probably not even a domesticated pet as they’d all likely die within a week or so if I don’t prioritize that. Sounds incredibly sad and lonely
