Hello and thank you for using JustAnswer. If your housemate is a danger to others and herself because of a mental health disorder than you can have her involuntarily hospitalized by just calling 911 and telling them of the situation. But if involuntary hospitalization is not an option and she refuses treatment there is not much you can do besides contacting an attorney to try to have her removed from the home for your safety or you can move out on your own.
I am very sorry, but if your housemate will not get treatment than you are going to have to focus on your health and safety now and do what is best for you and the others living in this home.
