I reread your OP about your neighbour. I agree with what Traveler said. For someone to turn 180 like that does indicate mental health trouble. She's behaving like that to everyone she knows so she's not singling you out to curse. Good for you on calling the police. Magic works best with mundane action(s). I hope you told your landlord about the loud music as well.

I suspect all that's going on here is how her energy is affecting you. I suggest cleanse yourself then your flat. After that, put up wards and protections on, or near, your wall that's closet to her flat. There are many ways to do that so google can help you get ideas. Get protection that you can wear, or carry with you, can help you cope with her negative energy that she's emitting.

As a side note, please don't worry about if she's stronger, better or etc with magic. Just because she's educated and experienced in spiritual matters does not make one a witch. To craft spells, you need a different knowledge base (and skill set) compared to spiritual development. I suspect she does not know how to craft any kind of a spell. She can work on her chakras (spiritual development) for all she wants but that's not a spell.
