The thing is: What do you expect when you leave? I thought about it for a long time. The thought that the grass is greener elsewhere? Or that you can tolerate everything better because it's not your "own" country? I look at the countries advertised and ask myself: would I feel more comfortable there, or comfortable at all?
I would rather shape my environment. I have moved a lot in my adult life. You take yourself and your problems with you and then there's also the fact that you feel like a stranger.
So let them go, but we create our home at home.
