I agree it is a terrible dilemma! I would feel the same way about
my cat. He can usually be fine on his own for several days. He could even go for more, if I had the automatic cat litter box. I'd let him stay at home where he's most comfortable, but would probably still call the vet to see if he could be boarded, just in case. We'll keep your cat and you/family/community in our prayers. Definitely keep us posted!
