I know that impulse. Like you don't even want to live in same country as some people. You want to be as far away as possible to escape their toxic influence. I used to and still do think like that but think there is a choice also. It's not an "easy" choice and often involves confronting impenetrable walls. But ultimately happiness is important and if going away is best way to be happy, who is anyone to say otherwise. But in my experience that can often mean escapism sometimes and ending up meeting the same kind of people or worse you tried to flee from.
