Hi Justin, I cured 3 and a half years ago. I had speech fears for a year after that. I still occasionally get a speech fear (I am talking once every couple of months).
Just 3 weeks ago I had a speech fear when hosting the SAM meeting, as I am not the greatest at public speaking, but I did not stutter. Bottom line, no matter how many fears will pop up in the future, I will not stutter.
I dare you to ask FLUENT people if they experience fears when giving a presentation of more than 30 people, as you said you do. I GUARANTEE you that most of them will say yes. So if fluent people have these fears, why are you being so hard on yourself?
