How to get away from my mom?

I'm feeling frustrated with my mom lately. Even though I'm 18, she still bombards me with a million questions every time I go out. For example, the other night I was hanging out with my coworkers until around 12:30am, and she blew up my phone, called my sister, aunt, grandma, and even the cops, thinking I was missing. She's always checking my bank account, snooping in my room, bathroom, and car. It's been really stressful for me, and I feel like she's always in my business. While I know some people suggest moving out, it's not feasible for me right now as I'm a dental hygienist student at a 2-year college without dorms. I'm considering dropping out to become a flight attendant just to get away from her, but I'm not sure what my next steps should be.
