I’m 22. I’ve just graduated and now I’m undertaking a masters degree. Like you I also have a severe stutter, exactly like you described. I majored in International Relations, a communications degree, because that’s what I like, it’s what I’m good at. It all comes down to that: what are you good at and what do you enjoy? Though important, the speech is secondary, because you’ll always live with a stutter to some degree, so in my opinion it’s best to go for the option you like because you’re going to stutter anyway. I have to say that my years in university have given me new ways to understand my speech, come to terms with it, push myself, explore, etc. I feel a much more confident person than I was at 18 when I had just started. My advice is that you write on a piece of paper all the things you’d like to do and start narrowing down. In the case you’re worried about your speech: Don’t choose something just because it involves less speaking. In the workplace you’ll always have to speak, there’s no going round that. Good luck, any doubt you can contact me!
