Cleansing yourself, and home. Then protecting yourself and home. I guess burning or getting rid of the seal you made helps to sever any ties the spirit has to you. Recite banishing prayers from a grimoire, or a Psalm for protection. Asking a higher ranking spirit for help. Where a protection talisman/amulet. Sprinkle rock salt around bed, windows, home, front, back and or bed room doors (I know that’s so “Supernatural” but it works for me). (IMG:

All that should work, I don’t see why a negative spirit would waste time fighting and suffering with you for no reason, when there are normal unprotected people out there.
