I need advice... should I run away?

I'm a 16 year old girl. I've just gotten off from school for summer. Last year I didn't have one at all because I was bedridden after a particularly bad surgery. I'm only a sophomore, but I'll be doing a year abroad in Sweden for my junior year. My mom is making me take the SATs before I go. And, I'm fine with that. But, she's also making me take three different SAT tutoring sessions... all 2 hours and thirty minutes long...A DAY! She also has been shoving her alma mater (UVA) down my throat since I became a freshman. I want to go to UK, and possibly become an orthopedic surgeon. But, she told me she wouldn't pay for that. UVA or nothing. I just want a few days... and I've told her that repeatedly. I just finished exams, and I'm fried. I make excellent grades, and am continually on the honor role even though I am in all honor classes. I told her the same thing again today, and she said that I should just leave because she does everything for me, and I don't appreciate anything. I do though! I always say thank you! ALWAYS! I just want some time off, and for her to stop force feeding me her ivy league bullshit. I can't ever go out.... I just want some freedom. So, should I take a stand, and leave for at least one night, or should I try to resolve the problem. Honestly, I'm leaning towards the rebellious side because I'm s mad. Help?
