Thank you for the information. They are not being abused by my brother as far as I can tell. My parents are managing somehow. My mother is seeing the doctor next Tuesday about two weeks after she hit her head. I'm hoping she will be ok. My father is working still because he wants to work and stay in shape. But, he depends on my mother to do all of the housework and other chores. He does nothing but his work which is commendable at his age. I think their dissatisfaction and unhappiness are causing me stress. I will let them be because they don't want to change their situation. I worry about them but there is nothing I can do to help them. I will leave them alone. I have to take care of myself and will try to do what I can if they ask me to help.
