Same here. I left my native country (family chose to move) when I was 8. By 12 or 13 I was probably more fluent in English than the original, although I continued to read, etc. I can still read, think a bit, help my family with duo lingo, but fluency would be a stretch so many years later. However, I have no doubt that if I moved back home, I could pick a fair amount up again in a few months. But I would probably forever be "teenage slang" non-fluent, as well as missing out on common idioms, etc. My father left his birthplace when he was 4 or 5, and only knows a few words of his first language.
