I began cooking for myself at 12 because my mother was hospitalized most of my adolescent life. I also had to cook for my father and brother and sister. Learned how to wash my own clothes, iron, etc.
If you graduated high school two years early, and you know your likes and dislikes in food, why not cook for yourself? It sounds like the housekeeper earns her wages without her cooking for you, so wait until she is out of the kitchen, open up a jar of red pasta sauce (check the ingredients) and open a box of angel hair pasta (check the ingredients), get a nice bread (check the ingredients), drizzle olive oil and crushed garlic, and you've made yourself an easy, tasty meal in 20 minutes tops!
Afterwards, clean the kitchen of any mess you made (if you're like me, I've totaled the kitchen even with boxed, prepared items!), because if you are going to college, you will need to learn to clean up after yourself and do chores, etc. I had to learn myself, and a thoughtful, giving person learns to do things for themselves, too. I'm not directing this at you, but at anyone going off to college, etc. It's just the nice thing to do, and it will make you more independent.
Growing up is hard enough - independence feels really good and "grown up."
