Hi, I'm a 27 year old non-smoking semi active woman. I have a pretty balanced diet, no allergies or asthma (that I know of). Recently I seem to have trouble catching my breath, I have lots of phlegm in my throat, a runny nose and seem to yawn a lot. I was diagnosed with panic anxiety but I don't think that's what it is because it constantly happens when I'm relaxed and resting as well as times of stress. Can you tell me what's wrong with me? Thanks, Yawny
