I really don't know what to say that hasn't already been said. If you can find a weapon... gun, knife, stick, improvise, make your own weapon, whatever... and you are legally allowed to injure or kill them for the sake of your own self-defense, that's what you should do. If not, and I'm really hesitant to say this because I have trust issues and possible legal problems with the police... get the police in on this. They might be able to help you, because as far as I know you probably don't have shit on your police records like I do.
