HELP!!!!!!

HELP NEEDED.

due to a medical emergency i was unable to attend to my finishing my bread making today.
my sponge was matured overnight and i should have completed the bulking up and baking stage today.
due to a medical emergency all day i was unable to finish those processes.

my big question is can i save my sponge and finish it tomorrow or has it had it.
it does smell quite beery and has a lot of bubbles on the surface, but it seems quite thin compared to how it normally is.
it is currently sitting at 70-80f in the airing cupboard in a bowl in a proving bag.

do i feed it and fridge it - fridge OR as is or just throw it away?

thanks

John
