I am so frusterated. I have no idea what to do about college. Please help...?

It would be unfortunate to loose the investment you've put in already- financially and credit-wise, but you're only 18, you should really be sure of what you're doing for the rest of your life. It'll be worth it in the long run to take the loss now and switch into a school which will allow more room to grow and learn about yourself. If you don't do it now, and you wait, and end up getting into something you're not 100% about, you'll definitely regret it
