Ohhhh, I'm so sorry to hear this. Four years without seeing two of your children is a long time. Friends and family leaving for a new world, one that does not welcome them. And this:

Host countries end up hating your kind. They could not care less about your motivations.
It's an almost fatal scenario, especially now that life for those who stayed has become more fragile, futile, ephemeral.

How can we help?
