Hey Doc, My Name Is Cristian And I'm 16 Years

Hey Doc, My name is Cristian and I'm 16 years old. My mother for 5 years now has had this problem that she's been talking to herself and saying things that aren't true. I've told some of my friends about what my mother has been doing and I've been told that she has schizophrenia. She talks to herself all day long. She won't go to a doctor and she's getting worse everyday. I don't know what to do Doc. Any suggestions?
