Why are relatives so toxic

I’m 28, living abroad with my brother, and we both have good jobs. Our parents are back in India. Growing up, I believed my mom’s side of the family was better than my dad’s side, but over time, I realized that my Masi and her two daughters are incredibly toxic. Despite not working or studying (even though money was never an issue), they constantly make me feel insecure about my looks, career, and life choices. They rely on financial support from my Maama and now my elder sister’s husband. What frustrates me the most is that people still adore them, even though they are the ones who spread negativity about others. My brother and I aren’t as close to our cousins because we’ve never indulged in gossip or family politics. We’ve always focused on getting a good education and building successful careers. We also take our parents on international vacations every year. Even though I contribute equally—or more—toward these trips, my relatives act as if only my brother pays. I love traveling and spend more than half of my salary on it, having visited three continents in the past two years. While my friends recognize my travel adventures, my relatives only comment on my looks. They also isolate my mom, excluding her from gatherings and not inviting her when they go out. When they split bills among themselves, they make sure we pay when we join them. I try to maintain a positive mindset through meditation, but they keep disrupting my peace. I genuinely dislike them, which is rare for me, and it’s affecting my mental well-being.
