Help Me Go To The University of Illinois!

After working extremely hard all through high school and receiving a 4.3 GPA and 31 ACT, I got accepted into my number one school - the University of Illinois.
When I originally enrolled in the University of Illinois, my parents were planning on helping me out with paying my housing installments and co-signing my loans for tuition. Recently, the circumstances have changed, and I no longer will be receiving financial help from them. I am stuck, I have several jobs and am trying my hardest to save up money, but with college being so expensive nowadays, it is getting very difficult and seems almost impossible that I will be able to go.
I do not know how much exactly I need, but I know that it is a high number, and I'm hoping that I can get some help towards it.
Every penny counts, thank you all so much :)
