She has not arranged for new housing, but insists she is "working on it." She has multiple physical and emotional problems: heart disease, pre-diabetes, fibromyalgia, hypochondria, emotional outbursts, depression, you-name-it, but has had no medical care for 8 + months. She takes some medication for heart, thyroid, and blood pressure, but also self-diagnoses and self-treats with vitamins and supplements - easily 25 or more pills a day. She is angry, opinionated, verbally abusive, secretive, frightened, and entitled. She is out of bed for 7-8 hours per day, at the most, and spends the majority of that time in the guest room with the door shut and locked. She is not a substance abuser, but spends most of her time reading or online. I am a single professional woman, still working at 66 in a job I love and intend to keep until at least 70. I also provide a home for our amazingly healthy mother. My sister has a minimal income, but a nice nest egg. She refuses to leave my home, and the situation is driving me and my mother to distraction. Any attempt to discuss the situation - even one sentence - is met with an explosion of anger and/or tears. She has said awful things to my mother and me. Legal action to remove her is hard for me to even contemplate, and would be hard on my mother, but both of us are thinking that this is the only option. We are worn out.
