Toxic mother/daughter relationship

My mom and I fight constantly. Esp ever since I got a boyfriend. I’m in nursing school and barely have money. I’m thankful for them for supporting me and I love her so much but this fighting is rlly bad. I want to have a good relationship with her but she always brings up rlly hurtful things. I know I have a mental issue and sometimes I am quirky and odd but I don’t think I’m a bad person. I feel like she doesn’t like me and wishes I was normal. I can be wrong sometimes too it’s not just her but she won’t admit or put herself in my shoes ever. I’m never listened to. Maybe that’s why I’m so damn quiet bc I was never ever listened to. I feel like my voice isn’t heard. She just screams and nitpicks everything but let’s my brother and dad get away with anything. It’s ridiculous. Idk what to do. Pls help. I want her to be my best friend but she’s pushing me away.
