Studying abroad was one of the best decisions that I made in college. I had the best time and it's an important learning and growing experience. I would suggest thinking through what country/city would be best for you. Language issues or other cultural issues might be tough. Although that is part of the whole process and it's meant to be uncomfortable in some ways you want to make sure you feel good about where you are living and studying. I studied in England because I knew that while I wanted to experience a different culture, I didn't want the added stress of a language barrier. And it turned out to be a great choice.
If finances are an issue I would suggest meeting with your counselor at school and have them walk you through scholarship and financial aid opportunities. There are a ton out there that might help you offset some of the expenses.
Best of luck! I hope you are able to have the study abroad experience.
