I'm bilingual, and I stutter in both languages. One thing I've found that works in the short term but will keep myself in eternal suffering is trying to hide my stuttering. That added stress of wanting to hide it and trying to appear fluent will distance you from how your body feels and behaves while you stutter. I know it's hard, but what's helped me a lot is getting closer to your my to notice which part of my body is contracting and stressing and try to relax those parts. I've found that in order to relax, I need to not care about what others think of me. Trying to hide it just keeps my focus in my mind and in that fear. Just my 2c.
