my roommate is trying to get me blacklisted

I connected with my roommate on the UBC class of 2023 page last year. We met at orientation and I thought things went well. Apparently not from her point of view. We're both not local but she's from BC and knows a some other people from her hometown in sororities and I'm from far out of BC and don't know nearly as many girls. Anyway, I found out she confided in someone that she doesn't like me at all and is going to try to get me blacklisted, especially from the "top 4" sororities where she has friends. I've done nothing wrong! Honestly, I think she's jealous of me. How much power does she have to ruin my recruitment? I'm scared!
