I remember experiencing awful homesickness when I went to France to stay with my penfriend and her grandmother. I hadn’t felt it when I went to stay at her parents’ home but her grandmother lived in a more remote place and it was so alien to my life experiences thus far and I just wanted to go home. I’d have been about 12 or 13 at the time. As an adult, I went to live in America for a while with my husband-to-be, and experienced no homesickness at all. I didn’t when I went away to college either. In fact I could barely stand to go home. However, just last year, I went to visit an aquaintance in the south of England (I’m in Scotland) and the hoemsickness hit hard. I suspect it was to do with the living conditions. I did not like where I was. And I didn’t have anyone I really felt comfortable talking to, but also couldn’t just escape to be on my own. So I’ve noticed that in both cases where I felt what I’ve described as homesickness, it was probably more that I just felt very uncomfortable about my surroundings and company and yearned to be somewhere that I didn’t feel that way. Is that the same as homesickness? Not sure.
