I know this sounds kind of stupid, but I'm having trouble pronouncing Japanese r's. Whenever I try to pronounce them I can't stop rolling my tongue. I have no idea why...I mean I try to pronounce the r's like they're in between l and r...but I still can't stop rolling them. My English r's are always normal. In fact, I never roll my tongue ever. I have no idea how I'm even capable of rolling my r's at all.
This is really frustrating me. Any ideas on how I can remedy this? I keep practicing, but maybe some specific techniques will help more?
