A story, some frustrations, and a few questions

Hello, all, once again. Many thanks go out to those of you who have taken the time to read my posts. It seems that support is easier found here than in my personal life, unfortuntely. Anyway, on to my story. A long time ago, probably around 2-3 years ago, I'd left my parent's house for a couple of days to spend the night at my cousin's house. I think I left because my parents were fighting and I didn't want to be around them. I came home shortly after. After my step dad left the house to pick up some things from the store, I walked into the kitchen where my mom sat at the table. I could tell something was bothering her, despite the fact that she doesn't like to share such things with anyone. I joined her at the table and asked her what was bothering her. She looked at me and said, "The voices were really bad yesterday." (Yesterday being the day/night I stayed at my cousin's place.) I wasn't really sure how to respond, but I felt bad. I told her she should've called me, and the discussion soon ended. It frustrates me that I'm the only one that my mom can talk to about this. Her first husband forced her off of her meds (I think she said she was taking Trazopam and Mellaril, not sure of the spelling, sorry). Years later, she met the man that she is now married to, and he doesn't give her support during rough periods because he doesn't believe that Schizophrenia exists. He thinks that she's making everything up. It worries me that I am no longer able to be there by her side because now I'm 3500 miles away. It's a shame that she should be treated like this, and I think more people should educate themselves on the disease, especially when living with a Schizophrenic. Ironically, I know find myself turning to her with my uncertainties as I go through what could be symptoms (I say could because I've not been seen by a doctor for tests yet) of the disease. My question is about psychosises. I was reading up on Prodome information and stumbled upon some information, but not all of my questions were answered. 1.Psychosises are the points in time where a person experiences such things as dilusions/hallucinations, right? 2.Is it uncommon for a Psychotic episode to last for several days to a week, or even longer? 3.In untreated indeviduals, is it possible for hallucinations (hearing voices) to persist indefinately? Thanks. -Rain
