Oh, it's the classic mental instability cause.
Actually, I am going through this with a friend right now. She was kicked in the head by a horse, and since then, while refusing treatment, has gone off the deep end. She's convinced that everyone she meets is a spy for the government or the devil and we are all here to bring her down. She went nuts and took all of her furniture and burned it, saying the government stuck spy equipment all over it. Her mother and I fear she is a ticking time bomb, and begged the doctors to do something, put her on treatment or have the authorities arrest her and force her for treatment on her brain injury, but they say their hands are tied until she physically harms herself or others, which hasn't happened yet. So, while I am not buying this nut job had some mental disorder, I can see why people are claiming that ignoring the mental health crisis going on this country is never going to be the answer.
