Patient discussion about delusion

Q. Give life to her please! Here is a really confusing question to you all. But your reply is a life for her. I know someone who is bipolar and she thinks that her ‘brother’ sexually molested her when they were kids. Can this be a delusion? Or hallucinating?

A. Im going to answer this question a little different;What if she is telling the truth,and her brother is planning on no body believing her? because she has this disease?---keep that in mind when you take her to the DR--mrfoot56
