i trained myself to break eye contact gently, still facing them but looking slightly to the side. I'll also switch my secondaries often: a gentle finger tap, saying "uhh" or "um", a gentle head nod, or even a little laugh at my inability to say a sound. it takes a great, gentle effort with a LOT of patience, but you can do it! you are probably normal, and you are not alone 🤟🏼
