Hello. I understand what you are going through. Its difficult sometimes to handle people with mental illness. By the description you have given, its quite obvious that your mother is suffering from serious mental illness probably psychosis
. However you failed to mention her age and since when she is having these symptoms. Most of the countries have laws pertaining to in-voluntary treatment of people with mental illness. May be you can contact your police or a local psychiatrist
who can guide you regarding the local legal matters and procedure for forced hospitalization. Such patients can harm others or some times themselves. Until you take some help, you be careful with her and take care of her properly.
Hope I am able to solve your concerns.
