Tomorrow is a little short notice. It will be how it will be, just try to keep your eye on the overall goal of getting yourself in front of the companies you want to get hired for, and making sure they take away your positives. You will stutter, but presumably you have things going for you that outweigh this speech impediment. I am not sure how severe your stutter is, but a mild stutter is no impediment to career success, and most employers know this. And for next time, my advice is desensitization. Try to go to as many social functions as you can, introduce yourself, talk about yourself, ask others about themselves. As you become desensitized, anxiety will start to play a smaller role in your stuttering, and hopefully it will lessen to the point where your speech therapy techniques will help you adequately.
