Hi, I've been in a dilemma regarding my sister-in-law for several years. Let me start by saying, my husband and I live with his father and half sister. His father is in his 60s, obese, and has alot of back pains, so we live with him to do chores around the house, make sure the lawn is mowed, run various errands, so on. The half sister, "Heather," does nothing. She is 30 years old, six years older than us. My husband said that ever since she was a kid, she was a primadonna brat, but when she got into highschool, she started using crystal meth. This altered her behavior further and more negatively, and after a couple abortions and the death of her mother (they were on bad terms with eachother at the time of her passing), she is where she is today. She screams all day, screaming out things like, "GET OUT!!!" or talking as if she's having a violent and negative conversation with someone, lots of threats, cursing, etc. She slams doors. She's said there's a ghost in our house, and she thinks it's her and my husband's mother (to clear the air, no one else has never experienced anything remotely paranormal in our house). Heather's four year old son has no father, and she was stripped of her parental rights after my husband and I caught her beating on him a month before his third birthday. According to the police report, she told police she was "beating the devil out of him." She has been told by a judge that if she wants a chance at getting her son back, she will have to go to counselling at the mental health center and show progress on her condition. Instead, she sits in her room all day in the dark, watching television, screaming and carrying on despite my husband's father's efforts to get her to go to her appointments or get a job. I feel her lack of social interaction is making her condition worse, yet she refuses to do anything at all. I think the lack of social interaction has also affected her mentally in other ways, like common sense or reasoning. Just an example, she'll try to make kool-aid, but only mix the powder, no sugar. As far as her physical health, she's gained an enormous amount of weight by not doing anything physical, and I think her eyesight is getting worse from sitting in the dark, watching tv, as now she has to squint at all times to see. I have told my husband that he needs to talk to his father about Heather and what to do with her. I've tried to be sympathetic to her condition but it hasn't done any good. After having to deal with her habitual lying, mood swings, in addition to the screaming, child beating, and so on, I feel what's best for her and us is for her father to give her an ultimatum: Get help or hit the road. My husband doesn't want to even bring it up to his father, because he thinks I'm being too harsh. I do not know how else to deal with this?
