Carma, You may just have to take her to a hosp. if you can get her to talk about the odd things she is thinking and saying in the er in front of the docs they will admit her for at least 48 hours and they will try to get her on meds and see if they can then get her to sign her self in before the 48 hours is up. What state are you in? All states have different laws I know the ones for Ohio and Florida if you are in one of those. But, you have to get her help Iknow that here in Ohio we have a state group that I have found very helpful. You are going to make her made because she is sick and cannot see anything she is saying as wrong but you have to use some tough love and do it. It was the hardest thing I have ever had to do but, she will only continue to get get worse with out help.
I hope this helps some and if I can help in any way please let me know.
