Dear Sir I can imagine it must be quite distressing for you. Feeling anxious all the time, having physical symptoms like shortness of breath, palpitations, feeling as if you are going to die are all symptoms of anxiety disorder.Anxiety disorders can be treated very effectively with a combination of medication and psychological therapy. You will also benefit from certain lifestyle techniques like meditation and calm breathing. Please see a psychiatrist for a detailed evaluation which will include physical examination and blood test to rule out any physical cause like thyroid abnormality..I am certain that you will feel better with right treatment and support.
