Tips for no contact while living the borderline

Title says it all. Im under so much trauma and stress from her last lash out, but I just started a new job and I have to finally be done with her so I can accomplish the things I feel like she subconsciously doesn’t want me to have.

I’m not her handler anymore when my dad goes away and she goes off the rails. Won’t even acknowledge her.

Any tips would be appreciated, I’m on my last straw
Soft paws on moonlight,
Whiskers twitch in silent dreams
Night purrs gently on
