My biggest fear was definitely understanding and how my Spanish would improve in the three weeks.
I had a lot of nerves leaving my parents, and the long plane rides, but fortunately, I was met up with my roommate in Texas! Other students apart from Sol Abroad were also on the flight, helping to calm my nerves. My nerves weren't completely settled until after the first week, but there isn't much to do about it.
After a week, it is easy to get comfortable, and the nerves wear off. I'd also been a bit nervous about my roommate, but I love her so much - we still have kept in touch! For my fear of understanding, it was quite challenging for me at first, but all you can possibly do is try your best!
It is completely natural to be nervous about the trip as well as the language aspect. Throughout the trip, I was nervous to voice my Spanish, but what I've learned and now regret is speaking as much Spanish as possible!
Take advantage of the trip! Don't be too shy - NO ONE is judging!
