Living alone in college T^T

To the college students here, how did you persuade your parents to let you live in a dorm? I talked to my mom, and she agreed to let me enroll in my desired college school, but my family will accompany me because we live in the province, and the college is in the capital. I've worked so hard to persuade my mom to let me attend this school, I'm a consistent honor student, and I was hoping to use that as leverage to persuade her that I won't be distracted while I dorm, (that didn't work) They have worries that I would become pregnant or use drugs, they do not trust me despite my grades,what should I do? any suggestions? (I'm grade 11 btw) Or not dorming jhust a tiny rental apartment, I just want to live alone while college, I don't want them to follow me anymore.
