Is there someone in the family or friends that could reach out to her? We went through a similar situation with our daughter and she wouldn't listen to us anymore. We found a family friend that was a clinical psychologist that she did listen to and got her help, diagnosis, meds, acceptance, etc. Maybe someone in her social circle that can get through to her?

Try this book...."an unquiet mind", was a great resource for our daughter and my wife and I as well.
