Wow! This is a perfect description of me when my depression is bad, also. Even when I am doing fairly well, I really just love to sleep. It is one time when I don't have to think, worry, or deal. Every couple of months or so, I will spend a whole day sleeping, especially if it had been a stressful week or I was feeling especially depressed. I have always been this way, and my mother was this way. I know if it lasts more than a day, then my depression is getting worse, but often, at least for me, a day in bed just makes me more able to face whatever is happening next. I am fortunate (depending on how you look at it!) -- I don't have a husband/significant other, and my children are out of the house -- so no one to remind me that "nothing is getting done" -- but it has affected past relationships. In answer to your question, I'm not sure if I would call in an "addiction", but include me in those who look at sleeping as a luxury!!
