Very, very familiar for me. I remember when in fifth grade in our class came new class teacher and she asked me almost same questions. I tried to say just my fckn name for thirty seconds, tried to set myself up for this seemingly simple action. In classroom were all my classmates including half the new guys and our parents. I was disgraced not only in front of them, but also in front of my mother, who knew about my stuttering, but anyway through her relaxed face I could see her disappointment. The more you think about stuttering, the more likely it will still happen. Of course, when events occur when we think we "should never stutter," we get very nervous and trigger speech blocks. The only option is not to think about it, even though you know that's impossible. All you have to do is 'finish stuttering' in the usual sense of the word. It is in vain to think that speech blocks are different from stuttering - the neurosis is so powerful that it gives you the mistaken idea that you can't do it. But you can. The next time you have a speech block, finish what you wanted to say without delay with all the repetition. Stuttering is a speech disability. Don't be embarrassed about stuttering and don't blame yourself for all the things that are out of your control, and stop trying to cover it up every time without success. I believe underestimating stuttering is what creates so-called speech blocks. I know it isn't easy. But believe me, at one day ou'll get so tired of it that you won't care. Good luck to you.
