Its back. That hollow chest feeling. Burping only helps for a moment. Today I felt lightheaded and dizzy, I went to dr in my office who said maybe I am coming down with the flu, but my vitals were fine. I want to not worry about it & move on, but its just not working. Even napping for an hour didnt help. I just feel like I am in a fog & I hate any chest discomfort b/c I always fear the worst. The doctors say I have GAD. I just feel like I am in a just about full blown panic mode all day. Anyone else get like this?
