[originaltext] Is it true that you will feel very excited and happy when you

Is it true that you will feel very excited and happy when you go to live in a new country? And will your life in this new country always be wonderful and exciting? Some specialists say that it is not easy to adjust to life in a new culture.
    They call the feelings which people experience when they come to a new environment "culture shock". Then, when the novelty wears off, they begin to hate the city, the country, the people, the apartment, and everything else in the new culture. In the final stage of culture shock, the newcomers begin to adjust to their surroundings and, as a result, enjoy their life more.
    Who experiences culture shock? Everyone does in some form or another. But culture shock comes as a surprise to most people. A lot of times, people with the worst culture shock are the people who never had any difficulties in their own countries. They were active and successful in their community. They had hobbies that they enjoyed. When they come to a new country, they do not have the same established positions or hobbies. They find themselves without a role, almost without an identity. They have to build a new self-image.
