You don't have to feel insulted. It's just an observation. You have to admit, that many of the gai-jin who stay in japan for a long time are effected by their time there. It's a stressful place to live, unless your in a large city surrounded by other ex-pats.
I knew a guy who lived in Ukraine and east Europe for five years, where outsiders aren't usially trusted. He imparted that the culture shock and difficulties in Japan are far more difficult in Japan.
