What do you do when you can't leave your home because your fighting with people

A 36 year old woman who is crazy like who would literally stab you jumped me a few weeks ago, her and her sister are after me and to be honest I am frightened to leave my home. I'm 18 and I feel like my life is destroyed because of this I'm not being a drama queen but its facts. I'm a quite girl I don't do anything to harm anybody, I can't even get a day time job because I'm paranoid they will come around. I don't want to go to the police because these people are nutters and have a big family and it will make matters worst. I live in a fairly small town so the chances of seeing them is high, I bearly leave the house and when I do I'm really petrified, please help what can I do. I can't move only unless I save. I've been told to face them but there really are scary people.
