How to understand and help people who have been forced to leave their homes because of the war
The first thing you need to know to show support: when people are in danger, they turn on a mode of "survival" (particularly, reactions "fight", "run" or "freeze", which are manifested differently in the behavior of all people).
It is thanks to this mode people were able to leave and now are relatively safe. But it cannot be "turned off" automatically, it sometimes continues to work even in a relatively safe area. Internally displaced people and refugees continue to "survive" in the areas where they find themselves.
