Do not discount the possibility that you could have developed anxiety issues. Many of us stop going out to eat because over time we subconsciously associated this with getting sick. Some get the same feeling just going to work. Celiac can fuel anxiety and that feeling can lead to many of the Celiac symptoms. It can be difficult to determine if you are having a true Celiac issue or an anxiety one.
I work from home as well and over time you can find yourself being home bound. If you do not get out as often as possible this can make it much worse. Someone will invite you over or you need to go to a work function and you get that instant gut twinge of anxiety.
