I love my mom but I dislike her

So I got my septum pierced (20F) a month ago and have it flipped up because of my mom. I decided to tell my mom yesterday because I want to bring it down. She wasn’t mad at me but she’s disappointed and she wants me to take it out and I don’t want to. She basically knelt down in front of me asking me to remove it, but I’m so tired of being told what to do. I’m a senior in college and I’m about to graduate, and I’ve kept up good grades. I can’t move out because I don’t have enough money and have a sister to help care for. I’m honestly so tired and can’t wait to be independent. There’s things she’s done I don’t agree with but I let it slide, why can’t she do the same?
