My husband was diagnosed with Lung Cancer more then a year ago and he has had the COPD for a very long time due to chain smoking. The diagnosis of Dementia has been about 1 year now. That is mild compared to the COPD and the Lung Cancer. The COPD causes him to sleep at least 15 hours or more a day. It is very very sad to see him fade away like this. But, maybe it is a blessing, as when he sleeps he has no effects from the Lung Cancer. I just don't know what to do to help him. 20 Years ago I had Non Hodgkins Lymphoma and I lived alone at that time. It was very difficult but here I am, Praise the Lord. Cancer is a very horrible thing to go through for sure. But, I know that God is in control and He will help us both get through this.
