A single word for the emotion of "relocation depression"

It's a term used to describe the feeling after you've relocated somewhere else, whether it be from a move to another city/country, a change in jobs to somewhere else, or a shift in lifestyle. I was wondering if there's a single word to describe the emotion some feel when experiencing relocation depression. When I finished my Bachelor's I felt a small sense of it, but I could not come up with the words to describe it, other than this term I found online.

Is there a single word that could describe the emotion felt when under "relocation depression"?

Relocation depression could be caused by many factors, i.e. trying to adjust yourself to new environment, fear of interacting with strangers and pressure to prove yourself to them, etc.

Relocation depression could be called Anxiety, more specifically Stranger Anxiety or Social Anxiety.

Anxiety is not the same as fear, which is a response to a real or perceived immediate threat;[4] whereas anxiety is the expectation of future threat. Anxiety is a feeling of fear, uneasiness, and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing...

Anxiety during social interactions, particularly between strangers, is common among young people. It may persist into adulthood and become social anxiety or social phobia. Stranger anxiety in small children is not considered a phobia. In adults, an excessive fear of other people is not a developmentally common stage; it is called social anxiety. According to Cutting, social phobics do not fear the crowd but the fact that they may be judged negatively.
