AIO Not getting an invite to Mother’s Day

Well to make it shorter than it could be I went over to my parents house on Monday to help my dad with some yard work (they’re getting older) and I asked them what we’re doing for Mother’s Day, well my mother (which we have a mending relationship) said “oh we didn’t think you would want to go, you never want to go to family stuff” (me and my girlfriend live 45 mins away and it’s hard to stuff) and I just asked her are you serious and she said there’s no room for reservations, sorry and I just lost it. Started screaming at the top of my lungs all the manipulative shit she did to me and my brother growing up,’why we are both fucked up, while my fathers telling me to calm down and she starts screaming at me, I started packing up my shit and just screaming fuck you bitch over and over and she goes I’m calling the police. Now my mom is a Karen to the max, like in the last 10 years she’s turned into an alcoholic mess who tries to be this glamorous person like her sister (which she never will, my aunts rich, we were never) she knows how to push my buttons. I smacked the phone out of her hand and her new iPhone landed in the dogs bowl and doesn’t work, and my dad told me to leave (which I was doing) but I was so hurt and in disbelief I couldn’t even think. I drove home in tears realizing I’ve never had a mother and yet I felt bad for my actions hitting her phone…I don’t think I’ve ever been that angry. Now I’m just so sad, and the gift I got her for Mother’s Day is going to my girls mom, but my dad texted me asking how I was and things and I just explained how hurt I was. And he’s an older guy who’s stuck in his ways, like depression, you’ll get over it! I’ve been crying for help my whole life and turned to substances in my 20s to numb myself and get through life, which really caused a wedge in my family. I know this wasn’t short but there’s a lot to it. Told my dad I’m done with family stuff and going no contact with mom, but I love my dad so much. He’s such a sweet person at heart it just sucks to see him tied to that woman who hasn’t showed me love in decades. Am I an asshole for wanting to go no contact with my family? My parents sister judges me even worse and everyone on my moms side talks to me like I’m braindead because of my drug use. I’ve been sober for 4 years. It’s been 4 days and they haven’t told my older brother who lives at home so I’m assuming she realizes she fucked up but AIO?
