I am sorry your having problems and it sounds like you have more than one reason to have your anxiety on the rise. As far as the time of digestion of that nasty new food, I would think it should clear your system in 24-48 hours depends on your digestive tract.
We are always here for you so you go right ahead and post whenever you want. Are you on a med for the anxiety?
I know the trips to the Drs. freak me out too and it is hard to stay calm when you are facing the unknown.
I try very hard to stay in the moment and not let my head keep worrying about what is coming down the road. I try to rationalize that I have no control over what is going to happen at the Drs. and that is why my anxiety is up. Does it work for me? Most of the time.
Please know I am here for you as well as all of the other wonderful members here in A & P
