I am not a native English speaker and I do remember when the shift happened. It got very frustrating sometimes, I often felt like leaving the English world for like one day so I wouldn’t have to struggle finding the words to talk to myself. Inversly, ten years later that’s what happens to me now if I speak my native language. I’m losing my mother tongue, my old friends and family even tell me that I don’t sound like I used to.
Always looking for the words you need even in thoughts gets annoying but after a few years like that, you learn more and it gets easier. In fact, once your thought process changes language, your learning curve becomes sharp. Fair trade for the inconveniences.
Nowadays, quite often I still can’t find the English words I need but I manage to express myself better and without brain stalls. The interruptions are what I call brain stalls. That’s when you can’t think further without that word you need. Of course you know what you want to say/think and it’s not that important to have the exact word(especially in thoughts)but it happens and it slows down your thought process. Very annoying that is.
