Culture shock happens in varying degrees, so be prepared to experience the W-curve of study abroad:
London doesn’t seem to have a large cultural difference from Richmond, Virginia. Both cities contain a diverse population, both are booming with creativity and art, and both are hubs for inspiration.
Like any larger capital city, there are thousands and thousands of people hurrying about and busy with their own lives, so diversity seems more accepted here than in Richmond. Although overall a liberal city, Richmond still certainly can be conservative in certain views.
Up until this point, I’ve really only felt homesickness once. It seems like studying abroad is somewhat of an emotional ride. The first initial weeks feel like one big vacation: you’re constantly meeting new people, your flatmates (roommates) go out and party constantly, you want to see and do almost everything you can in your new environment. On the second part, things slowly start to ease down.
