My 77 year old mom and 88 year old step father live alone but need help. I live 2500 miles away. My sweet parents are still living in their home in Boise. My sister is handicapped and in a care facility that does a terrible job taking care of her. Parents visit her almost every day but have no control over her care. Mom has dementia but not diagnosed. Dad says she's fine just a little forgetful. He refuses to tell me what will happen if he passes before she does. Other than another sister that is estranged from the family I'm the only child. I live in Houston where I'm based as a flight attendant. I cannot move to Boise. Nor can I quit work. I'm extreme worried and concerned about what will happen to my mother AND my sister if dad should pass away. They have NO savings. I have no way to pay for care. I can't stand the thought of burdening society but I don't have any idea where to go for guidance? Dad keeps saying that she will die first or they will die together "Notebook" style. Mom forgets her meds, forgets things I say within five minutes, heart problems, diabetic, knee and back issues. Has had over 40 surgeries under general anesthetic through her life time. My only brother passed away very suddenly a year ago at age 53...Thoughts?
