Grieving for your culture incorporates everything that you left behind. This is primarily your identity but also includes tangible things that you started missing. Apart from social losses, one may mourn for the food, the atmosphere in your neighborhood, speaking your language, the jokes, the interests people had in you, accessibilities to your hobbies, the climate, the light touch you had with your day-to-day life, and everything that mattered to you or that started to matter after leaving it behind.
