First off, clean your house. Cleanse it, and realize that all that energy is going away. Sweep your floor, put salt around your house.
Then get a White and black candle, and banish/protection incense. First walk around with the banishing incense (coco, ect) and with the candle. Chant to yourself that all bad will leave and only good will remain. Then grab the white candle and incense and say only good will come in.
Lastly do a protection ritual, and leave a blue candle burning.This restores peace, so whenever you see it, believe that peace will be restored!
