Save money at a Cal State or go to my number one school which is a UC?!?

           As of now I am applying to Cal State Long Beach, Cal State Fullerton, and University of California Irvine. My sophomore year of high school, I made it my goal to get accepted into UCI. I want to get out of the Long Beach/Bellflower area and move to a new city while I attend college. However the closer I get to graduation the more hesitant I feel about actually wanting to go to UCI. After discussing with my parents our finical situation I sadly learned that my family and I are unable to afford any UC without having to take out student loans. I currently have a brother at Cal State Long Beach and a sister who dorms and attends UC Riverside. The cost of tuition annually for my parents is $40,000. My parents did not set enough aside to allow me to go to attend and dorm at a UC. For the past two years I was looking forward to leaving my small home in Bellflower and venture out into a larger city and immerse myself into the campus life. I have to come to terms with attending one of the two nearby Cal States (Long Beach or Fullerton). I had worked so hard my four years of high school, I took various amount of advanced placement classes, became apart of a sport, as well as various amount of clubs even taking high officer positions. My family have pushed to became the best I can be so I could be able to attend a great school just like my sister, however knowing that my only option to attend a UC is through taking out student loans scares me. I have been warned by teachers and by administration to avoid such matter at all cost if possible. However since it is my own education my parents have given me the decision of whether or not to take out student loans. My parents are very supportive, however I don't want to put my family or I through this financial hardship. But then again education is an investment and if I'm serious about my education then this trouble should only be temporary.
