I'm really sorry for you, friend; that sounds like a horrible experience. But I'm also amazed that you've achieved what you have. You're at one of the best universities in your country, that's an enormous achievement and one that you should celebrate. And you've done it in spite of an affliction that, at times, brings us all to our knees. You're doing brilliantly. I know it must feel like your world is closing in right now because of this setback, and I don't want to diminish that at all, but I'm really inspired whenever I hear of stutterers picking themselves up and putting themselves back out there. Don't let this club be the blow that beats you down. Public speaking beats people who don't stutter all the time. You're not alone, and you've overcome buckets of stuff to get to where you are now. Don't give up.
