Congrats on taking that step forward and doing something you would otherwise try and avoid! I'm 28, and I've been blocking since I was four as well. I am now a test engineer for a ship building company and I speak in front of groups daily in one way or another, either morning meetings or procedure briefs that can take upwards of 1 hour or so. For me, reading aloud or saying something very specific triggers my blocking to the point where it can be very severe. I don't, however, block as much if I'm talking 'in the moment' if that makes sense. So to fix my issue the best I can, I try to prepare and learn the information that I will be presenting as best I can, and talk candidly about it in front of groups, glancing at notes and things occasionally to stay on track. I am usually reluctant to do things that I don't have to (like order food over the phone) but when it's my job to speak in front of others, I make myself feel confident about it! I tell my self that I can do it, and that I won't block or stutter at all. This came after years of being too scared to take risks and step out of my box. The fact that you're already stepping out of your box and taking risks, shows that you have the confidence to do what you want to do. >tl;dr I've stuttered for a while too. I think you're making great choices and actively taking risks to build confidence! Try to prepare for your classes as much as possible and talk off the cuff (if that helps at all, otherwise don't do that). Congrats on making progressive life choices! edit: spelling and other things.
