Welcome! And if I may advise you shortly, don't go this avoidance path.. It's just gonna get worse. The avoidance techniques will grow so will your fear of speaking/stuttering and after a while the guilt of sacrificing your grades, goals because of you stutter will creep in and won't let you rest. There may not be a chance for us to speak fluently one day but there's still chance for us to feel okay about it. And you won't be if you'll avoid facing your stuttering and continue "saving" everyone around you from it. You'll just get more ashamed about it and boy, does it eat you alive. Not everything we achieve in life is built on fluent speech, you can gain self confidence just by being brave in not letting your stutter decide your fate.
