Get your mother committed for psychiatric observation today.
She is a danger to herself and to others. Call her GP immediately, get a lawyer, call the cops, whatever it takes, just get her in the hospital. She could unintentionally kill someone in this state, especially if she's driving. Do you want to live with that? If she won't take care of herself once out of the hospital, have her declared incompetent to handle her own affairs and take charge of her finances so you can make sure her property taxes and bills are paid.
I'm so sorry you and your family are going through this, whatever is causing it. Take care of yourselves and each other during this time, as well. Please consider counseling for yourselves, especially if you end up in caretaker roles. I've seen firsthand with my mother how devastating caretaking can be emotionally.
