When a parent’s anger turns into hurtful prayers against us

Assalamu Alaikom. I need to get this off my chest. My mother has a lot of narcissistic traits-it’s not just me saying this; our extended family sees it too, which is really sad. My parents’ marriage is tough; they argue daily, and it often ends with broken things around the house-a pot, a vase, even the TV. My mom usually starts it; she’s always on edge. Growing up, it’s been like tiptoeing on eggshells around her. The reason I’m sharing this is that whenever I get overwhelmed by her outbursts and try to talk to her about how it’s hurting all of us, including my baby sister, she turns to making dua against me. She prays I find no happiness, that I face the same struggles she does, and that I never succeed. I just want to know if her duas are even valid in this situation. They had another fight just now, and I ended up with more bad duas on my head, so I left to stay with my grandmother. I’m so drained and don’t know what to do anymore. Every Islamic reminder says you must never be disrespectful to your parents, but she acts like we don’t exist when she’s in the middle of these huge fights. I don’t think my mother cares at all about how this affects us.
