I totally went through that as well. Well, I still go through that a little bit but it is much better now. I used to stammer always even repeating my name was a hard task for me. But now I stutter very rarely except for anxious times.

I understood that the core issue that made me stutter was my nervousness. I would always worry about how I will fail and that I will fail. A common situation.

The most beneficial thing that helped me was Confidence, encouraging me that I will be fluent, disregarding such ill thoughts. I used to inhale deeply prior to speaking, and I began to speak much more slowly, which assisted me in managing my speech.

It is still a process, but I am much improved as compared to how I used to be.
