I am searching for a replacement for “death-sick” (or is it “dead-sick”) from the sentence:
“A stigmatized physician falls into an organ donor scheme through which for every human organ he delivers his death-sick daughter gets an extra month of life.”
His daughter suffers from a rare brain disease, for which there is no treatment. I found “brainsick,” which means nuts. “Nauseous, invalid, sickish, anemic” are all too soft for this case.
