Is wife ridiculous lazy or something is wrong with her?

I know that you said that she was not depressed but it sure sounds like she may be headed that way. She sounds like she may have some type of fatigue disorder, this can be from a variety of medical conditions including depression. Talk to her about this and see if maybe she has been feeling "down". I am not a medical doctor or anything so any opinion that I give is just that, an opinion. Best of luck to you
