So, Oikophobia.
Oikophobia (from the Greek oikos, meaning home or fatherland, and phobos, meaning fear) is a psychiatric term denoting an obsessive fear of returning home, to one's family. In a narrow sense, it can be a fear of the physical space of one's home, while in a broader sense, it can be a dislike of one's own culture or home country.
Have you ever experienced this? Or have your friends or family members? What triggered it? How do you cope with these fears? Are you struggling with them?
I've recently become very interested in this topic and want to hear other people's opinions.
