Oh wow.
Well, I have never lived in LA, but I have visited a lot, and it is my greatest fantasy to live there, so I can be encouraging, and you can take it with as big a grain of salt as you like.
LA is totally beautiful and totally cool. It has everything you want in a city (OK, except decent public transit), but it has the beautiful ocean and mountains and perfect weather. It has all the cultural attractions of a city, and also what surprised me is that it's really a pretty old place, so it has all the pleasures of urban decay that I didn't expect to find in California. There is interesting history and charming neighborhoods, and, I know no one else cares, all the Japanese food and shopping you could ever want without moving to Japan.
As a New Yorker I can't believe I am saying this, but another cool thing about LA is that is kind of like New York in that it's one of those places that's really central to our culture (even if you feel like you have to put 'culture' in quotes.) You feel like you are at the center of something and not out in the sticks.
Oranges grow on trees there, and avocados. Flowers bloom in the middle of winter. Everyone is happy there, even the people who work in, like, coffee bars, because they live in LA and they never have to worry about it snowing on them. And they can go just a little way and look at the ocean and it makes them calm and happy.
Yeah, OK, this is an East Coaster talking... you already have a lot of this in Hawaii, but, if you don't have a job in Hawaii, that's not relevant, right?
I know none of this answers your practical questions. Just a little waxing rhapsodic about the possibility. It sounds like maybe youall could use a slightly unrealistic glow of positive feelings about the place...
I am so jealous that you have this opportunity that to you seems like a terrible exile... isn't life crazy unfair?
