I’m 20 years old with no privacy help!

My mother decided to invade my room and privacy and found adult toys, pregnancy test and lingerie i never had any privacy as a kid or teenager but i expected to have it as an adult i don’t even know how i feel so i just cry. I’m a full time college student this is my first semester I don’t graduate until December 2023 i don’t work enough hours and only get $9 an hour that’s not enough to live on my own but I really need to get out of this house and far away from my mother it’s not just invading my privacy but always fighting and feeling like home isn’t home and always feel on edge around her and like i can’t do anything. I don’t know what to do anymore i started thinking about dropping out and take that time into working so i can get a lot of money to move out but i really don’t want to to have to do that but i can’t take another second living with her
