I am 24 year old female with a history of panic attacks and high anxiety. I have been a pack-a-day smoker since I was 18. Lately I have been experiencing a shortness of breath that doesn't seem to go away and is making my anxiety worse. I have been to the doctor and expressed my concern about this, but they seem to be chalking it all up to my anxiety symptoms. My o2 stats have been in the normal range (usually 97-98%), but I feel I am not breathing normally. I finally decided that I can't smoke anymore with these symptoms, and haven't had a cigarette in 48 hours. Now my lungs are burning a bit and I can feel a cough coming on. What should I do about the shortness of breath? Is this normal with anxiety, or should I be doing more about it?
