I watched a Lady die from this, but she would not quit smoking. I always thought to myself I would never have to worry about this as I never smoked in my life. So in my late 40s i got a case of bronchitis that was mis diagnosed. I actually ended up with a lung disease called Boop. Bronchiolitis obliterans of organized pneumonia. I ended up losing 40% of my lungs. I underwent treatments for it and actually was cured from it and was just left with asthma. Last year my husband of 51 years passed away, the next thing I knew my lung volume went down. I am now on oxygen, 2 liters. I had this disease for 24 years. I was always very active before the disease and after it stabilized, now I worry how long I got.
