Well, basically, you should try speech therapy again. But probably not with the same therapist. You see, therapy is inherently variant, depending on where the client is at and where the therapist is at. Also, you should stick to it, and not expect progress in a while, because this sort of thing is hard to get a handle on. Stutterers can do just about anything you can think of. All that's different is some of the sounds and how they come out. :)
