My mom has dementia, some type that makes the patient very aggressive and physically abusive. She is also verbally and emotionally abusive as well as ungrateful(for example, I do everything for her yet she says I do nothing for her). She is also extremely stubborn and spiteful. But she is like this only with me. She is very sweet and reasonable with everyone else. No one will help me take care of her because they don't think anything is wrong with her except forgetfulness. I am having a hard time taking care of my own health problems(diabetes, kidney failure, and increasing vision loss among them) because of the demands of her care. Sometimes I feel the only way out is to kill myself. Is this typical of dementia?
