I Feel Insecure Around My Sister

I always feel insecure whenever I am with my sister. She is the only sister I have, yet I still feel insecure around her. I feel like she looks down on me. Anything I do does not feel okay or good to her, always finding fault in me. I commented on a post on X asking people for my house rent money, and I commented N80k, only for her to enter my DM on WhatsApp telling me I should clear my phone and return it to her. Mind you, she is the one that got me this phone because the old one I was using was faulty. Ever since she got me this phone, we are always having one or two issues. I am just tired and fed up. Please give me advice. What should I do? Because I am not returning any phone.
