I overcame my stuttering problem.
I was a bad stutterer when I was very young, 5 or 6ish, and I couldn't pronounce my R's either. I sounded like a nervous kid from Boston. lol
Well, speech therapy was given to me by my school to help with my "Boston accent", and during the course of that, I overcame my stuttering. It took a few years, but I got there.
Pretty cool, huh?
I remember there were 2 young ladies helping me out with this. Looking back, I'm pretty sure they were high school students doing this for extra credits. College prep, and all. They did a great job though.
