@boredsilly– Hello. You sound so frustrated, and I so sorry. When there aren't answers and solutions it can be devastating, but not hopeless. I am a lung cancer survivor of over 21 years. Cardioversion straightened out your heart beat from an arrhythmia to a normal beat. Have you doctors explained any reasons for your shortness of breath? Do you also have cancer? You haven't said. What kind is it? You also mentioned getting off the wagon. Does this mean that you have stopped drinking?
