Need some reassurance

I have been suffering from emetophobia for sometime now, and got fp a month ago (v* about 8 times in a night) and have been incredibly anxious ever since. Been struggling to sleep and feeling n* on and off for the past month (due to anxiety).

However, I have been spiralling since Monday. I got a plain baguette on Monday, to have on the side of some soup. Just before eating it, I got convinced that someone with noro had touched the baguette and that I would get ill. I have been n* since then (due to the anxiety) but no other symptoms (been almost 40 hours). Although I am pretty sure it is all in my head but cannot rest.

Any tips or reassurance would be much appreciated. Anyone been through something similar? Did you get ill?
