Answer:
Return syndrome.
Explanation:
The return syndrome is the phenomenon that explains the sadness, the feeling of inadequacy and the difficulty of readjusting the culture and customs of your home country, after you have spent a long period of time in another country.
You are adapted to the culture and customs of your home country, however, when you spend a lot of time in other countries with a culture and cost different from yours, you will begin to adapt to the culture and customs of those new countries. The more time you spend in that country, the more adapted you will be.
When you return to your country you will be out of touch with your native culture and customs and may have difficulties adapting, and may feel sad and inadequate to your country of origin. This is the return syndrome.
