If you’re studying computer science, prestige won’t make a bit of difference. Bachelors degrees, especially in Computer Science, are pretty well standardized and very employable out of college. Also, going out of state is about triple the cost of tuition. Unless your parents can pay the massive tuition or are willing to co-sign large private student loans(VERY bad idea), it’s going to be out of reach anyway.
I didn’t get my first pick in college either, but I’m doing well as a computer professional. If you’re feeling depressed, it could simply be depression. That’s very common with college students. A few regular therapy sessions can make a world of difference in just a couple of months. I would take a visit to the health center.
