Sorry to here about your friend. It does sound like she may be paranoia schizophrenia however, I am not a Dr.
I too know someone who is a paranoia schizophrenia and to see them as "normal" and then... to lose their mind.....it is heart wrenching. I have often wondered what went wrong, and I know that most times a condition like this one is treated physcologicaly and the symptoms are just medicated over leaving the victim most often in a worsen state. ( this is what happened to my sister-in-law)
I believe that the brain is quite often overlooked as a physical organ (most times it is only the mind that is treated) and symptoms like this can be a result of toxi-molecular damage to the brain. Dr. Gant MD,Phd, NMD has done exstensive research on brain wellness and has treated 1,000 of people successfully with conditions all related to brain wellness. He is truly an amazing, compassionate man and is devoted to helping people. I know he is currently doing a research study on Bipolar. He also conducts various Pilot Research Projects that your friend might qualify.
The information obtained by the Pilot Research Project will be used to support the feasibility of larger more controlled studies about neuronutrition. The staff at Pilot Research Project hope that this information about will hasten us to the day when non pharmaceutical, natural, science-based, safe and inexpensive treatments with nutritional supplements become the treatments of first resort for physical and psychological problems, instead of being treatments of last resort as is currently the case.
