Should I do this? PLEASE HELP? THIS IS MY DREAM?

Without knowing anything about your talent level, I always say that if you have the means to follow your dream then nothing should stop you. My parents spent a lot of money on my private education growing up, and even though I ended up at a state college and am still only earning entry-level wages they would say it was worth the money. I would say in your case this is even more true because it could help you really achieve your dream. Good luck!
