I would focus on what's important in life. Education, health, maybe sports, work, etc. Don't let your stutter consume you. If it wasn't that it would be something else taking up headspace that no one but you really thinks about. I have a few techniques I think I may share in a video because it would be too much to type but there is no cure so nerves will tend to override any technique sometimes but the more we don't care, put ourselves out there anyway and focus on what is really important, the rest will sort itself out. No one can escape growing pains, we are just built to be stronger!
