My mother has COPD and her doctor has ordered oxygen for her. She is 61yrs old and still working (a pretty tiresome, physically demanding job.) Does anyone have any advice or suggestions from your experiences? She is scared and not sure what to expect. I myself am worried and have many questions. The need for oxygen will make it impossible for her to continue working in her current job... should she consider filing for disability or early retirement? Does BGE (Maryland electric supplier) offer a program that limits the bill due to the increase of electricity usage?
