How to deal with people who believe in magic?

Last time I told you about my mother putting a paper on which magic words were written so that I'll bewitched to marry someone.I was afraid and people on yahoo said I should fear nothing and that these are superstitions.Two days ago, my mother invited the magician and his wife to visit us and make a spell on me.I deliberately went out of the house until they left.Today ,my mother will pay for another magic and she'll put something in my food or in my room(I heard her asking my father for money to buy this magic and he agreed).I am saving money to leave the house ,but what can I do right now? I hate this atmosphere at home and I do not want to live in fear(I'm 22 years old, christian and I do not believe in such things).Please help
