The lack of bidets and the state of public restrooms generally

Learning to practice mindfulness, gratitude and related, going to therapy or trying medication is a lot easier than moving because you’re unhappy. Also the idea that Paris is a monoculture is absurd. OP could find hundreds if not thousands of Americans to hang with in Paris at any given moment, not to mention countless other people who don’t behave like stereotypical Parisians.

And I don’t mean to be critical, but you said it yourself. You moved from somewhere “bad” to somewhere “better” and you’re still unhappy, though blaming it on the previous place. You are the common denominator here.

Happiness is objectively not equally related to internal vs external factors.
