Hi there. I know how tough university can be. Pulling all nighters, being exhausted and then stuttering worse when there's a presentation. :/ I'm not the best person to give advice, more just telling you you aren't alone in your hesitation. I will tell you this. Look to the future. I didn't pursue my area of study and one of the reasons was presentation burn out (actually, fear). But if you want to get into business, if that's your passion, then do it! Yes, school will suck due to the concentration of work and presentation after presentation, but that's the worst part. School's the hardest part for most people, let alone stutterers. But you have to rough the waters and do what you need to do, to work in a field that you are happy about :) something you like. You know how college is a make it or break it time? You can think of this in the same way of how you're going to approach your life as a stutterer. Be brave, be bold, and get through it. Achieve what you set out to do. You can do it.
