Refusing to eat totally is indeed very rude. In fact, it might be taken as an insult if you were the main guest.
However, you can always ask for a plate and a spoon, fill the plate and eat the way you are used to. This will totally save the situation and will be understood positively since people know how foreigners eat, but not eating at all is something you should avoid.
By the way, asking for a spoon or fork is totally normal even if you weren’t a foreigner.
