I am so stressed, she nearly killed my friend!!!?

This woman, Louise's mum is a raging lunatic! It's terrible that you have to feel so frightened that you don't even want to leave the house. If that woman lays one finger on any of you, you need to report her. And have her ARRESTED. There is something horribly wrong with her, and if something happens to you or she threatens you like that again, report her IMMEDIATELY. You and your friends should not have to feel that she is going to come after you. You HAVE to do something!
