You have been living in a new country for a few months, and you have unpacked your suitcases and boxes. You have read all kinds of information about housing, transportation, work, schools, health, taxes, paperwork. Little by little things fall into place and you do your best to settle down as quickly as possible, to feel at home and feel comfortable.
And how do you feel? Have you stopped to think about it? Moving is considered a highly stressful experience, as is changing jobs, looking for a job, changing countries, etc. In your case, all in one. You are going through a lot of changes around you with more demands than usual and this new environment demands adaptation.
In some cases, expatriates seek therapy motivated in part by the frustration of being isolated. Whatever the problems that lead to starting therapy, the most frequent causes are that people do not have friends (or not so close) or close family with whom they can confide about their current difficulties. For anyone, the pressure that builds up from not being able to share struggles can be maddening. This seems to be further intensified for people living abroad.
Although most people manage to cope with the negative aspects of migration due to the existence of other positive aspects, migration is a risk factor for mental health due to migratory stress or mourning, called the immigrant syndrome or Ulysses syndrome.
People use a series of psychological defense mechanisms or errors in order to help them cope with the new situation abroad. They are not in themselves negative but when they are plentiful they radically distort the view we have of reality and prevent us from adapting and preparing for migratory grief.
