Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you should consult pulmonologist and get done1. Clinical examination of respiratory system. 2. Chest x-ray. 3. PUT (pulmonary function test)4. Your symptoms are suggestive of pulmonary diseases (bronchitis, asthma) more. So get done above-mentioned investigation to rule out asthma and bronchitis. You are also very obese. So cardiac causes can also be possible.  So get done ECG rule cardiac cause. So better to first diagnose yourself and then start appropriate treatment. And lose weight because obesity is not good for health.
