10 years of speech therapy did literally nothing for me...i even went outside of school to a hospital to get help, which just turned out to be a waste of money. I have accepted there is no cure and I just have to deal with it. I actually kind of have a phobia of reaching out to people about my stutter. One on one therapy was like the most I can do. At the point that im at now, just talking about my stuttering with other people makes me cringe for some reason, just extremely uncomfortable. I tried a group therapy one time and I could not do it and left halfway through. Right now I just have the mentality that I should just write everything down instead of embarrassing myself in front of countless people trying to say words that I cant....and yes, I am extremely embarrassed by my stutter in public situations. I was even still made fun of in college for it, it doesnt get better like most people will say. I might give some books a read
