I'm sorry you're going though this scary time. This sounds like active psychosis. I've been in a similar position before. My brother was diagnosed with schizophrenia in 2006, but he was having delusions and hallucinations in 2005. Unfortunately, your hands are tied. It's hard to convince them to get help and even then you can't do the treatment for them.

Remember: if she is a danger to herself or to others you need to call 911. That's the only way to get an involuntary hospitalization (and psych evaluation). She would be hospitalized from 3-7 days before she's released, during which time she will hopefully be medicated and her positive symptoms will remit -- unless it turns out this isn't the onset of a mental illness but in fact something physical, something metabolic, which is a possibility. The age of onset of SZ is later in women than it is in men.

An invaluable source of information and support for me has been NAMI.
