Thank you for the detailed reply, Miss Aida!
You're right about therapy being part of the answer to dealing with a narcissistic parent. I had an excellent therapist as a teenager who helped me accept that life isn't always fair, sometimes people get stuck in shitty situations that they really don't deserve, and it's best to concentrate on the things in your life that you can change. It helped a lot. I go back for a little more counselling each time I discover some other way in which my warped upbringing warped me as a person, which isn't always fun but it is necessary. 'Lay counselling' (i.e. talking to friends who have some understanding of these kind of issues) also helps a lot.
As for the legal side of things, that's unlikely to happen. Unfortunately police say "it's a family matter" and won't get involved, even when they're handed enough verifiable evidence that a stalking conviction would easily stick, if the stalker wasn't a family member. My best friend is a lawyer and has done everything she can to help me, but ultimately family ties are privileged over the law even by those supposed to uphold it; breaking laws against stalking is ignored because, "she's your mother, of course she wants to contact you and know what you're doing."
And yes, you're also right that the stress of dealing with her has taken a toll on my health, but that's a subject for some other time.
As for the hoodoo aspects of it...
Is there anything I'd need to change in the Cut and Clear spell on that page, to make it apply a family member instead of an unrelated person? (The spell says it's for a lover or friend, although the black walnut spell says it can be used for a family member.)
Is there anything I could do to increase the power of the spell, since the bond between mother and child tends to be a lot stronger than that between unrelated people, or even less closely related relatives? Or would that be a bad idea?
Or is Cut and Clear plus Banishing the traditional way to cut ties with a close relative who you need out of your life, i.e. the two combined provide the strength to remove a troublesome parent from your life?
Also, I'm new to hoodoo so I try to do one thing at a time. Would it be bad if it takes me a little while (like a few weeks) to do the Fiery Wall of Protection, after the Cut and Clear and Banishing work?
Sorry for all the questions; I'm still learning, obviously.
And thank you so much for your help with this. I would really like her out of my life, but having no contact with her for almost eight years hasn't been enough to do it; there's still some sort of connection there that lets her send horrible energy my way from time to time. At this point, I figure rootwork is more likely to break that connection than one more therapist, no matter how skilled.
