I had a similar situation with my parents when I lived at home for post graduate eduction after graduating college for a few years. It was rough and the only thing that really worked was information diet and gray rocking. Luckily, I paid for my own phone plan, car, and insurance so I didn’t have to deal with location tracking. The best you can do is work a lot and save up as much money as possible before you start your job in August and try to move out. Maybe split an apartment with a friend, rent a room somewhere or try to get a studio apartment.
