Moving is a stressor in it's own right but it can trigger anxiety because it affects multiple areas of your life when you have to do it. A decision to move can bring about a level of fear to what is unknown, thoughts of loosing connection with friends or loved ones, the anxiety of not being able to navigate from place to place in your new area, whether you will be able to experience a sense of normalcy and how much will the move shake up your finances. Be encouraged, that whether you are moving for a job or to be closer to family, remember that there was a reason for the move and all of the anxiety will be worth it in the end.
