If you feel like a foreigner, it means you don't belong there. But travelling is good experience, even if it isn't the best.
One day, you'll be home. And then it'll be worth it.

You belong to a different world
you move on a different level

look at some of the people you feel a stranger to
and count your blessings lol

I assumed that was the nature of most all people.
It sounds natural to feel odd in unknown areas. Most everyone dresses differently. Accents, sounds decorations?
I don't like to travel. I have a home I love. A place I feel I belong. Pets and family. No I like being where I know where everything is.
But THAT is my opinion.

I would tell them to stop looking outside for what you're looking for is inside. you'll end up messing up the outside too. Be patient, what you're looking for, your home & where you belong - is patiently waiting for you too. Be precise, the hardships are a must to remain there.

to enjoy their unique perspective.

Id be like ok anyways...
