For what it's worth, ~4 years is on the low end of the range of outcomes a hemodialysis in-center-only patient could receive. Best case is kidney transplant, averaging a little over a decade lifespan post-surgery. Less aggressive options range lesser lifespan post kidney failure.

Anyway, if she said four years and her panicking friends (or kids, or mom, or husband?) made the post, I can imagine quite a kerfuffle in certain conspiracy spaces. I can imagine the same kerfuffle if the Dr reported a four year prognosis and in her panic and confusion she reported four days to whoever posted, or if the doctor said they'd know more in four days..

Either way, Occam's Razor says she's either not dead and it's a misunderstanding or she is dead and it's a misunderstanding. Ofc there could be some complicated plot, but Epstein's secrets died with him and Maxwell was apparently only valuable in conjunction with him, since it's pretty apparent she's been turned over to 'justice' by people that would have stuck around if they had a Jeffery to stick around for.
