Don't take it too hard. Each of us here face this problem. Your parents are the first of any to have accepted you. They understand you. Do not get tensed. Breathe in, calm down. And then try to communicate. If you stutter, try again. Your parents have all the patience for you. Never have a doubt on that. Hope you come to a peace with your stutter. That's how I learnt to survive my personal and professional life. It is not going to be easy, but things would definitely get better once you come to accept it. Good day.
