Well, first I need you to know that I do not believe any mental or emotional disease is inborn/genetic. She is a victim of programming by mixed messages, but in the programming are threats of punishments, probably by God, but it could simply be situational, like parents being caught in a sort of "damned if you don't, and damned if you do". People who were parented badly parent badly, because of mirror neurons. No point in blaming, just understanding. We take as normal the way we are treated, but when normal has mixed messages, we short circuit and sometimes out of fear (threats). Second, I have seen that schizophrenic parents are often good with babies and start to lose it with toddlers. That means they raise children with a strong foundation of self-worth gained by the beginning of life, where identity is created, but after that, the child is on his or her own a lot, even taking care of mom, which can tap you out by the time you reach adulthood. So, you would need to find a very rare doctor who believes symptoms are related to cause (like paranoia being related to threats, cause and effect is replaced by religiosity turning into superstition in a young child, mystifying technology). I'd ask her what the voices say. Is that she is always on call? So, she just hears her name? Is she hearing, "God will punish you when you least expect it," or something that would cause her symptoms. Cause and effect. There are very few such clinicians, because most psychologists are "brought up on" 50/50 genetics, and teach bandaids more than remedying cause. Good luck young man. I'm impressed with you. Maybe some day you can take this concern to a profession and become a psychologist, but in the meantime, take care of yourself, mostly. You deserve it. Go with God.
