Hi, schizophrenia is a serious but controllable illness. There are medications available for it. If your gf has not seen a psychiatrist (this is a medical doctor) she MUST see one to get the appropriate medicines.

As for you, her loving boyfriend, please understand that this illness is not for the faint-of-heart. It is difficult for the patient and difficult for the ones who love him/her. Think carefully as to what you are strong enough to handle in your emotional make-up. This doesn't mean that you have to abandon your gf, but it does mean that it will cause a strain on you both--even if she gets the proper medicines and therapy for her potential illness. Good luck.
