Try creating the Traingle Spirit Trap of Hekate designed by Jason Miller, it has a creation, consecration, embuing, and use instructions in his his book of Defensive Magic. It will help set precautions next time aswell.
For now conjure forth energy from yourself as a shield, have it gathering mass near your heart chakra, let the energy expand from you to form a protective pod thats intention to block other energy and attacks. Continuing focuss steady enough to maintain the shield and its protection, but it will fade in effectivity within time anyway, this will protect you from psychic and spiritual attacks till you can banish, placify with offerings, honor your oath, or entrap and remove. Things do not get better without dealing with it, and smudge and cleanse the home to clear away negative energies they feed upon until you again deal with returning it to the original source (whether plane of existence or curse from magus).
