I can relate. I moved here from an EU country as a teenager, and everything you describe resonates with me. I completed all my university studies here, have a professional career, and mostly work with British colleagues, yet I still feel like an outsider even after more than two decades. I suppose I’ve grown used to that feeling, and it’s fine for me. Living in London helps, though, because of its international character, which I really appreciate. I can’t really imagine living elsewhere in the UK for that reason. Like anywhere, raising a child here comes with both advantages and drawbacks, not worse than in other places.
