I think I'm into fourth stage now.
When I go back to visit my country,I feel like I don't belong there anymore.After a couple of decades here(hey,I'm not that old,I married young),I'm so much adjusted and Japanized in a lot of way(like missing my nightly ofuro and misoshiru) that I sometimes have these identity crisis...
But, I can never consider myself Japanese,yet. Noticed my avatar? Tabibito or Traveller.
FirstHousePooka, I suggest you find yourself a girlfriend/boyfriend.
