I think one of the anxiety elements of travel is that actually you know it is your mind travelling, as well as your body.
And ‘though you might get a bit anxious about how your body copes, really it is how your mind copes that worries us most. We are scared more by how we think we might think than we think we might do.
In going somewhere else we become the alien, we usually start to see ourselves as someone on the outside (unless we are just totally egocentric, like ‘English rules’ OK?).
The answer probably lies in just being. If we can just be who we are, then almost everyone will be welcoming.
Mostly, I think, the human race is universally accepted. We share the same planet, we are all the same people, really.
