The old lump in the throat. One of the most common symptoms of anxiety. I think everybody gets it at one point or another. No magic cure for it. It does go away by itself. Just try and not focus on it. By doing that you are feeding the fear. That oddly enough is just part of the fear. So the less attention we give it the quicker it will go away. I know it can be hard to eat as well when you have this. Just pick certain types of food for now and I am sure it will clear up soon enough.
