My SIL is/was like this.She passed in January. For about 2 months before she died, I was going down there & helping her get rid of crap & cleaning things up. I could see what her future held. I knew there was no way any EMT or morgue could ever get in her house. She was finally put in a home for her remaining days. The mess is left to her husband. We have offered to come and help clean up the place. I guess he's doing it little by little. But, it is a sickness...sad,sad,sad.....
