Lack of Appetite = Panic

Having some panic today--don't know why. Wasn't hungry for lunch, but decided to eat at 4pm because that's when my husband was eating. After I ate, i started to get panicky. Why? I think because I was eating chicken in balsamic vinegar sauce, and I was afraid that the vinegar might trigger stomach upset. I ate the same thing for dinner the night before and I was fine. I've eating this dish several times before, and I was fine. But this is the nature of my anxiety. I tried to distract myself with housework and eventually it got better, and now it is better still.
