AIO for expecting my mother to treat me differently at 18?

I (18F) grew up in a pretty religious household, but I am not particularly religious myself. My brothers (28M and 21M) have both moved out, leaving me the last one. My mother (53F) is a single parent and is very lonely (i work a lot and am still in school).

Now comes the part where I dont know if I'm overreacting. I love concerts, and have been to 3 over the last 6 months or so. Being that the city where everyone tours is about an hour away from where I live, I like to book airbnbs to stay in after the concert with my concert buddies: my boyfriend (20M) and his best friend (20M). When I returned after my last concert on 2/1/26, my mom told me I am no longer allowed to go to concerts unless she is present or if i come home right after. The city is KNOWN for having terrible traffic, and I don't love the idea of driving back after a concert, since I'm a moshpit type of gal. This hurt me a lot, as I don't get to enjoy myself a lot with my busy schedule. I told her this and she essentially told me to suck it up.

Another thing I don't know if I'm overreacting about is the following situation. My boyfriend and I recently got caught in a not so SFW position (not sex but still NSFW) and my mom was, understandably, upset. She told me I was not allowed to see him anymore. I put my foot down and told her she wasn't going to do that to me. She switched the narrative, and I am now grounded for one month and not allowed to go to my boyfriends house indefinitely. She speaks very ill about my boyfriend and has for a long time, as his parents are very hands off and never taught him how to drive, so I'm doing it (he also did not live at home from 16-18 years old, not that it matters much). I feel like this is very disrespectful, but she says I do not deserve respect basically.

Another instance, she came into my room yelling at me at 5:00 AM when she knew I had to be up early about my boyfriend not having a car. She continued to yell at me and berate him and me until she left for work at 6:00 AM.

I want to move out because of her blatant disrespect of me, my hobbies, and my status as a legal adult. She still demands my location, has screen time on my phone, and forces me to go to church outings (will ground me if I don't go). Would I be overreacting if I moved out because of this? I also have a lot of guilt for leaving and being independent because she's not well mentally and I genuinely feel bad for her. I'm stuck. Am I overreacting for wanting to move out and expecting her to treat me like an adult? I know I'm barely an adult.
