How do you all deal?

I feel like having a borderline mother is EXHAUSTING. in our latest bout, she broke her word that she had given me and then tried to spin it as if I was doing something wrong by being upset about it. She told me that im "invalidating her" and "continuing the intergenerational trauma"

I'm at such a loss for how to deal. Like I don't want to cut her out of my life, but also - give me a fucking break. It's a never ending waiting game for the next time she inappropriately loses it.
