Mary,
I know it's hard, but hang in there. Once you have surgery, you won't be hungry for a while. Just try to clear your head and relax for now.
I was pretty hungry right before surgery but the swelling and tenderness of your abdomen totally takes your appetite away. Just follow the advice of your doctor and his staff when it comes to liquids.
In a couple of months, you will have bacon again, but be forewarned that it may not taste the same. I have found that some foods I used to love don't love me anymore like pizza and surprisingly, cheese and eggs. You will need to experiment and see how bacon works for you, but you're a long way off from that. Just remember to listen to your body and be kind to yourself.
Best,
Amanda
