Can you tell her that what she is saying is hurtful? Without disagreement and with compassion for her state of mind? Is she aware that she is experiencing a psychosis, and that these thoughts and accusations are paranoia and delusional? Can you get some guidance from her doctors on how to handle these things? I am so sorry for what you are going through.. and for she and her daughter, your family... this sounds very painful indeed. I hope she gets well soon. Wish I had some good advice for you. :/ ((((Hugs)))))
