It will not TOTALLY disappear, but if you keep your hopes high and practice sometimes (I know that's hard but you got to accept it), I assure you that your speech fluency will get better! I'm a 15 year-old stutterer myself, and I know how it feels like when you want to express yourself but can't.. Well all I can say is try to stay positive as much as you can, and always remember that you aren't alone in this world; there's a lot of people like you and me who have this little problem😊
