I'm living in South Korea right now, and I can say that I have never seen that here. Everyone dresses very well and classy.
Kinda makes me feel underdressed half the time.

In fact, I haven't met anyone who has taught in Korea who also knew even a little about the language.

as for getting around,...

Anyways, this probably won't entirely be helpful, but the length of healthy grieving/depression lasts about a year.
My point is... don't TRY to get over it. Only time will help.
