Switching high schools senior year..

So I live in Louisiana and am a junior in high school with about a month left until summer. I want to go to the University of Houston for college, you of H is in Texas though. If I am an out-of-state student I will have to pay about $10,000 more than...

in-state students would have to pay. I am considering leaving my current high school to live with my cousin in Texas and go to school with her so I can be considered a Texas resident (They consider you a resident after you live in Texas for 12 consecutive months).
The school I am at now is okay. It's in a small town which I do not like, but I have a few friends that I would be a little sad to leave. Also I would be leaving my mother, father, and two sisters. Now think about this for a minute. I would be leaving for senior year, then I would attend college for four years and dental school for two more; next year would be the last year with my family and living in the home I have been in for about seven years, but if I leave next year I have about two months left here. That makes me a little sad, which then makes me question doing this.
I really think that the smartest move would be to go to my cousin's, and go to school with her. I mean it would save me about $20,000 of student loans.
So my questions for you:
1.) Any advice?
2.) What would you do if you were in my shoes?

1. Yes, talk to your friends and family, to get a buch of different perspectives on the idea. Also talk to school counselors in your school, to decide wether or not this is the best option.
2. I would do what I suggested.

on the one hand, I would go live with my cousin to save the money. It's not like you will never see your friends and family again. You can always come home on the weekends and on winter and spring break and also for summer. the truth is, when college starts, you start to branch away from your family anyway. you spend more time away from the house. and you find a job and want to spend a lot of your free time with your friends and such that you don't see your family a whole lot anyway. This is a major step, and it is part of growing up. You're not going to live with your family forever, and this is a good of a time as any to take that step. Also, you would be doing the mature thing and saving 20 grand in educational loans (which is great!). You don' t want to be paying off your loans for 15 years after you are out of school.

And on the other hand, there are lots of good schools in your state, and there is really no need to go to you of T if you can get the same education without having to move.
