Just keep it positive. Maybe a little gift basket of bath and bodyworks things for her may make her feel better enough to use her things. One more think, she may be able to see and hear the things you say about her behind her back as well. I will never ever call a fellow human being "the disgusting one". A lesson learned from a time before I was born. Please have compassion and calmness toward her. This a chance to make someone who lives in missery, feel like a human being who counts.
