Do you cleanse your home? :) I find that when negative energy is around, creating a 'safe place' full of positive energy is wonderful. Use sage or sandalwood incense to purify your home, and bury black tourmaline in the four corners of your property to neutralize negative energy. :) You can also try meditating to strengthen your chakras, and thwn use them to create a strong auric field.
