This is a really hard decision... Should I go for it? PLEASE HELP? THIS IS MY DREAM...MY FUTURE?

Do it! This is a great Opportunity for you. It will probably only be a once in a life time opportunity. And it will be well worth the money because if you do become succesful with this school and become famous and all that then you will get money and be able to help your parents. GO FOR IT! Good luck to you.
