Just want to move out already!

I’m 17, turning 18 at the end of June and I’m a senior in high school. I have a job, I pay for my phone, my car and pitch in for groceries. I live with my mom and my two younger sisters (ages 12 and 7).

I’ve been in a relationship with my boyfriend for almost 4 years and this past year we started being sexually active. I’ve talked with my mom about it even before we did anything and she took me to the doctor to get on birth control (which I also pay for) and for the last few months she’s been getting on my nerves. She’s always wanting to know what we do, how we do it, ect like I don’t want to talk about that with anyone, especially not my mom!

I’m a good student, top 3% of my senior class. Quality for the dean’s scholarship, and she thinks I’m throwing my life away because I don’t want to go to college. I was offered a full time position as a dance teacher at my studio, which has been my dream for years and she says “who studies hard and have grades like you do just to become a lame dance teacher”.

She also keeps nagging me about my weight, says I should eat more, I’m too thin, I’m not gaining weight like a normal teenager... I’m about to lose it y’all.

She’s a pediatric nurse. Because she has knowledge in this field she thinks I really have a problem but how do I make her understand I’M FINE? I just want her to get off my case and leave me alone. Every time I try to bring it up it always ends up in a fight and her in tears saying she doesn’t know who I am anymore. I’m growing up, I’m changing and I’m not really sure she understands. Can’t wait to get the fuck outta here.
