Is she on any medications, recreational drugs, or has there been any significant changes in her lifestyle? You can also check www.webmd.com for information regarding these symptoms, but yes I would try to get her to a doctor, even call her doctor yourself if you can with your concerns...maybe the doctor could call her in on a "check up" that she didn't realize she needed and she could schedule an appointment with her doctor. Hope that helps at all, and good luck hopefully she overcomes this paranoid state soon.
