That's awesome man. I'm a bit older than you but I also found that the only way to get over stuttering and axiety is to lean into the fear. "Feel the fear and do it anyway." When we run from things and avoid speaking situations the anxiety just builds up and when we inevitably have to do the speaking - it's a disaster. Don't fall back into the old patterns of avoidance - keep pushing yourself out of your comfort zone and you'll find you can do anything - and you'll even start to stutter less as a result because you won't be thinking about stuttering all the time!
