At this time,studying abroad may not be a wise choice for you in light of your anxiety, but also in light of the possibility of required isolation & limited activities due to the pandemic which might raise your level of anxiety.
P.S. One of the posts below reminded me of an anxiety laden student from Princeton University whom I encountered during one of my study abroad trips in college. The student–Brendan Frasier’s look-alike–flew about 27 hours to Hong Kong. Stayed one or two days, then flew back after his anxiety overwhelmed him. He then returned a week later & remained for the entire 15 week semester. He endured at least 71 hours of flying in just 9 days.
