Defeated husband has fallen into a downward spiral

DEAR ABBY: My husband is miserable. Five years ago, he was fired from his job of more than 25 years, and the small issues he had with depression, alcohol and smoking have multiplied exponentially. He sleeps until 10 or 11 a.m., showers only two or three times a week, rarely eats and has a drink in his hand by 4 or 5 p.m. every day. He now suffers from COPD but has no plans to quit smoking. He would never consider therapy.
