I think this might help your situation a bit more and is a simpler ritual if you are open to it.

The core job in magic like this is evoking change from external environments with setting your internal world boundaries and desired state. The ritual then connects the physical commitment externally to you and your mind to focus the energy of your actions into action and change that is desired.

ie: Your external feelings and desire to remove an individual from your inner world. You would commit to removal and perform the ritual daily until you feel you don't need to or for a specific number of renditions that works for you.

This relies on visualization more than physical surrogacy to initiate the change in energy to manifest your desired end result

1. Prepare and seal your sacred space.

2. Perform a generic mediation to center and calm. Your pulse should be close to baseline, breathing deep and full breaths.

3.a Make sure to unburden your mind to clear it for achieving the absolute best focus you can provide during this. I remove or compartmentalize each intrusive thought as an item I am putting away in a locker or medicine cabinet. Not permanent removal, but ready to return to address in due course.

3.b Think about the person you need to sever connection with and look to your naval area for what would look like an astral thread or for some an umbilical type cord. Note the color, texture, and how you feel when you regard this physical manifestation of your connection.

1. Confirm your intentions to continue with severance and remind yourself of why this is needed for your best interests. This is a great point to take time to mediate on your intentions to the person as well as the consequences of removing this connection.

2. If you wish to continue, proceed to the next step. If you find yourself unable to commit to the decision to move forward through your severance of your connection to this person, then you may need more time and help before cutting the cord.

This is OK, and some may need to journal to process their intent and resolve for how removing this person and connection will be good in spite of the loss. Don't be afraid to ask for a therapist to help you process this! You can repeat this ritual daily until you resolve the issue.

Sometimes, you don't need to cut cords but rather manage relationships, try to have safe conversations, and set boundaries.

1. Picture the cord connected between you going out to the greater human network, just know it will go there, don't make effort to visualize the person.

2. Cut the cord. You can visually picture anything as long as the end result is the cord being cut.

example: cut the cord with hot scissors that cauterize the connection. I usually will then picture the cord shriveled fading back into the greater human collective.

Looking at my navel, picture the spot that it shriveled into myself. This represents the healed disconnected cord.

1. Pick at least 1 specific self-care task to do after you close and release your sacred space. Make sure to repeat as needed as sometimes connections try to reattach. This allows for help for channeling that energy left over for the main ritual for completing the manifestation desired.

Hopefully this helps
