What (I think) cgstutter is trying to say that you shouldn't give a fuck what people think about you. Presentation and stuttering? Go for it. Speaking through the phone? Just do it. I know this is a bit cheesy and easier said than done. But I can guarantee you, it will boost your confidence and with that the potential to become a more confident and naturally speaker grows every day. And with the right therapy/theraptist you can get really far. Just don't try drugs or vague articles about cureness for stuttering. Such a thing doesn't exists.
