I'm not an expert, but I did deal with a bipolar husband. If she doesn't get her hallucinations under control, she's not likely to be able to take care of herself and get help.

My husband had to take meds for a long time. If he didn't, he went nuts and was impossible to deal with. Luckily, he wasn't too destructive, but he did spend every cent we had one day.

The meds for bipolar are quite good. I was lucky. The meds for schizophrenia can have unpleasant side effects, so she's not crazy not to want to take them, but there may be no choice.

I would strongly suggest that you include some consultation with a mental health professional in your search for help. In her current state, she may not be any condition to take other sorts of help.
