question: My grand mother had severe asthma. I am a 28 years old unmarried female and I never had asthma symptoms before. My father passed away 4 months ago and since then I am  under a lot of mental pressure/ stress. I work long hours and ours is a very polluted city. For the last 2/ 3 weeks I have been suffering from severe cough..both dry cough and productive cough, but no temperature or severe shortness of breathe. I had taken cough suppressants, but they didn't work. What might be the diagnosis?
