All of life’s most difficult and stressful moments involve some sort of change.
From births to deaths, to moving house or moving country, to illness and growing older, all change involves a loss, which can be either painful or sometimes cathartic, as well as the introduction of something new, which can be exciting and or disorientating.
In terms of changing country, the two main areas that can cause the most disruption are the loss of supports, and the changing of social norms. The the things that supported you, helped you through difficult times are gone, and it takes time to find the new ones. And while doing this the society that once valued one kind of action and thought, may now value something very different.
