I know it's not what you want to hear, but just embrace it and dive in - it will work out for you. I'm an engineer and I remember the absolute terror of my first interviews, getting hired and having to meet 100 new people, talking in meetings, giving presentations, all of it. 8 years later, I can tell you it gets better. Hell, I still stutter in meetings and phone calls to this day, but it doesn't bother me one bit. Don't let your stutter define your life, my friend.
