Do you learn other languages and how does this affect your stuttering? / Ranting about my problem. I'm 17 and I've stuttered off and on again since I was 5 or something. I learn German in school since the first grade and English since the fifth. I think this has a downsite and an upside. The usually mild stutter turns into severe blocks when I'm speaking either of the languages, but this exact factor makes me way more confident in my native language and blocks become shorter and less noticeable. I think that the stuttering in foreign languages comes from three factors in my case: insecurity in grammar (German, of course), insecurity in pronounciation/accents etc. (English) and being able to . Have you experienced anything similar? Tips on the issue are welcome too. You can skip this part, because it's basically me rambling about my life as a stutterer. I have a problem with anxiousness since an early age. I am nervous about posting stuff online, the way I dress, talking to strangers or girls, trying new food / music / clothes etc. I think that this is the cause of my stutter, contrary to the popular belief that anxiety is a side-effect, because it has existed in times my stutter didn't.

When I say I stutter on and off again, I mean whole years of stuttering and whole years of speaking freely. Before what I believe is the third period of my life stuttering (which seems to be the longest and toughest one of all, because I realize the effect on my life), I even participated in a rhetoric club and took part in a reading competition, where I had to read before hundreds of schoolmates and teachers. Sorry, if I made it too long, but I really needed to write this whole thing down. If something seems unclear, I'll try to give explanations.
