I need to go to college far away, help?

For my whole life, my family has moved every few years and every time we move, my parents expect me to do as they please and go where they want me to go. As I've grown up, I have started to move away from my parents stereotypical kid they want. Now, living in Virginia, soon to be Hoover, Alabama, I have chosen where I want to go to college and I'll do whatever it takes to get there. My dream school, where I have wanted to go for years, is the College of Charleston. Unfortunately, my parents expect me to go to Auburn or Alabama. While those are great schools, it's not where I want to go. I should have the grades, test scores, etc. but my parents are stone-walling me. They don't want to pay for the expense to go there. I have volunteered to do as my sister is doing and take out student loans for the rest of the expense they won't pay. But, they won't budge. Does anyone have any ideas? Honestly, I just need some advice. Thanks for reading and any advice.
