Gallbladder dilemma.

I am hungry. But my gall bladder has been hurting more and more for the past few hours (since ~8pm). Do I:
a) sit here being hungry, as eating runs the risk of horrible sickness later
or b) eat something with no fat in it, as not eating makes me miserable now?

It's one of those damned-if-you-do-and-damned-if-you-don't kind of things. I'll probably regret it whatever I do.
