#sigil help

Its a maternal bond, and the spell I've been using likely needs to be renewed. If anyone has any suggestions or thoughts to help a witch out that'd be fantastic. I'm more a kitchen witch than a banishment witch, so this side of my craft inst as strong... Nor is my knowledge of it.

Honestly... I just want her out of my life. She’s done harm so often, and even my best dame friends said she sounds like she’s being manipulative with her reaching out. I was very angry when I initially opened the envelopes, and to be honest. I’m still pretty rage filled over it. It hurts, a lot. And I just want to sever the ties as cleanly as I can. Let the bond break. 

The initial spell that I used was simple:

“Break the tie

That makes the bond

Say farewell

And move along”

I do feel like it isn’t enough, but at the same time. I also feel like to put more effort into it would be more than she deserves. I know I should put more into it if I want it to stick and that it feels like I more halfassed it the first go-round. Since I need to renew it anyways... Might as well go the whole nine yards with it. I know we’re past the more strong time for letting go, but. There’s a few more power times coming up.

Any thoughts, advice, or help on this would be appreciated.
