Hi, I got your chief complaint. There can be several reasons for this: - Anxiety as you say it can cause pain in the chest, breathing difficulty and fatigue. Other reasons can be: - An iron deficiency which can cause the same symptoms. - Any respiratory tract infection and heart disease. But your history suggests your problem is most likely from anxiety. I suggest you get an appointment with a psychiatrist and also a general physician. Maybe you need drug therapy for some time. I also suggest you take the light morning walk, engage with friends and family, avoid living alone and take fresh fruits. It will relieve you more anxiety and nutrient deficiency. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Soheel Hussain Zargar, Dentist
