My sister has COPD and is on oxygen. She can only walk for short bouts. She lies to the Dr that she is no longer smoking. She is close to being home bound. I have no idea how to save her from herself. I love her and idolized her my entire life. I'm wondering if she has given up? I don't want to treat as if she can't make her own decisions. I'm so emotionally exhausted as to how to proceed. Any advice?
Accept that this is what sne wants to do. If she wants to quit, she will. You can explain that it’s breaking your heart to watch her kill herself one cigarette at a time, but don’t expect it to make much difference. .
As other posters have said, the damage to her lungs has already been done, and COPD is not reversible, but is instead progressive.
Focus your energy instead on convincing her to make sure her oxygen is turned completely off prior to lighting up. I personally know a very sweet gentleman who died in a flash fire caused by smoking with his oxygen on. I can only imagine what a horrible way that would be to go!!
