Upon considering the scenario you described, my first thoughts were on how lonely an experience that would be.

That's the point. You can't be understood to a gratifying degree by people who don't share your culture, and simple words aren't going to fix the disconnect.

helpful and caring people that don't understand what's wrong can't provide very effective support.

If you saw someone from another country looking starved and miserable, you couldn't buy them food and direct them to shelter?

Loneliness means anything from not having enough people to chat with today to not having a soulmate who understands and affirms your every view.
