how to stop someone from making u feel insecure

I’m 20 and my cousin is 17. We’re roommates and know almost everything about each other, but it’s complicated. She helps me in many ways, yet often makes me feel bad and insecure for not knowing certain things. She judges me for things she does herself but idk somehow, shed make her thing completely normal . She studies political science and does debates, and it feels like she’s always trying to argue with me and act superior. I’m not great at defending my points, and it’s exhausting. I usually don’t get insecure about what people say, but it’s like she has so much control over my life. It feels toxic, yet I keep telling her things. And then the other day she’d come up and talk about the things I’ve done, saying I’m 20 and don’t have enough knowledge to live. i wanna have upper hand.
