The drama never ends

I’m (28F) ready to scream after these texts 1. From my mom & 2&3 from her husband. Backstory: my mom has been especially unhinged & awful recently. My brother hasn’t talked to her in months (not sure why she thinks he would come to Christmas based on this alone), she got into a huge fight with my aunt proceeded to call her a mean girl and blocked her and her kids on FB (she hasn’t told me anything about this though I only know because my aunt told me). She smacked me upside the back of the head last time I saw her and now completely denies that even happened & her husband recently called me cursing me out(I have the whole conversation recorded because I know I have to have proof of what they say to me since they deny everything). She lives states and away and decided to fly in on Christmas although I have told her I will be spending Christmas at my aunts house with my cousins and grandmother. I have already told them my plans yet they decided to ignore it and make reservations anyway & now it’s all woe is me. Sorry but I don’t feel bad for the woman who ran off to live states away with a man when her kids were teenagers, who has ruined yet another family relationship, who allows her husband to speak to me like so, who used to tell me “oh well it’s MY time now” when I was a little kid and was upset about her not being present. She taught me to live without her and create my own support system & now it seems the tables aren’t so fun when they turn. My dad (the most amazing parent & support I had) died in April of 2023 & they continuously try to use it against me to act like I’m unstable & it sickens me because I’m doing pretty damn ok for losing the only parent I had in my corner. I just want off this absolute crazy train and I’ve tried so hard not to go no contact but I truly don’t see any option anymore. I refuse to miss out on memories with my extended family because she cannot get along with anyone and demands my time. It makes me so angry (surprised? No.) she completely ignores how hard the holidays are for me after losing my dad & how I want a normal family holiday - not spending it at a restaurant because she decided to fly in.
