I'm so sorry you're going through this, and I truly empathize. I had a coworker who preached Zen and treating others with kindness, when she actually did NOT. She spoke terribly to and downright screamed at clients, vendors, others in the office and our team members - especially me - and the boss wouldn't do anything about it. I eventually had a breakdown because of her and left shortly after. She was the meanest, most aggressive and vile persons I've ever known in my life. I actually DO know witchcraft, but I only do white magick. Black magick, hexes, torture spells and the like will only reflect that back to you three times. (Rule of Three.) Voodoo/Hoodoo are closed practices, only handed down through generations <- just a little PSA. I know you don't want to, but send the bully love from your heart chakra.
