One of the main reasons why settling in a new city can be difficult is that it involves change and it is human nature to resist change. But a lot has to change when you join a university in a different city. You are not just changing houses; you are changing your physical environment, neighbors, friends, lifestyle, and even your daily routine. As such, the new reality is not something you are going to get used to in a day or two. Instead of allowing the anxiety that comes as you adjust to a new environment to overcrowd your judgment, you need to accept that what you are going through is normal, and instead, give yourself time to acclimatize. You just need to organize your stuff, create a new routine, and visit as many places in the city as you can. Remember that everyone is different, and therefore, you may take longer or shorter than other people to get used to life in the new city.
