My boyfriend’s sister is a borderline schizophrenic who gets worse everyday. She is 41 and is seriously out of touch with reality. She believes she is a cop, which she is not, and even tries to arrest people at the library with a fake badge she got from Google on her phone. She also thinks she’s a lawyer who does all sorts of cases, thinking she’s commissioned by the state. Again, she is not, she says she has a paralegal but there has never been one on file. She refuses to get treatment or even acknowledge she has a disability. How can we get her out of our life?
