I had a major stressfull event today it made my anxiety sky high, I have not been able to eat all day, ive felt like a zombie and now that ive gotten to bed my body is dead tired, my head is hurting a bit, have only eaten a small portion of ramen &amp; I feel nauseated. I have not had time to focus on my anxiety and I have not made it a priority either. So is it possible to get a delayed reaction?
