Answer:
culture shock
Step-by-step explanation:
It seems that Shelly is most likely experiencing culture shock. This is a set of feelings that occurs to most individuals when they move to a location that is very different than their home. Since Shelly moved from the US to China and the culture is completely different, it causes Shelly to not feel comfortable in this new location. Individuals experiencing culture shock experience many distinct feelings but ultimately adjust to the new environment and begin getting comfortable in this new location.
