Open conversation about toxic parents

All my life I've dealt with my toxic mother... emotional abuse, verbal abuse, physical abuse, falling out, letting time pass by, running when she calls only for her to still be the same mean, domineering and selfish person that is rubbing past feuds in my face and bringing negativity in my life. My bff and I are going through the exact same thing at the exact same time then I saw this meme. I'm tired of the same ole thing so how do I really cut my mother off for good? My only condition of not cutting her off would be that she starts some long, intense therapy highly unlikely but those are my terms. I live an hour away from her so this shouldn't be hard but my anxiety is through the roof just thinking about this. It'll help to hear similar experiences.
