I'm sorry but there is no medicine or cure for stuttering. There are some ways to handle it a bit but that's not my "area of expertise". I really wish you good luck and i hope someone with better advice will comment. But know that you're not alone. About 1% of the world population stutters and even if it's hard to believe it, it's true. If you really wantto see how many people stutter just like you do, i'd advise you to check out our discord, the link is in the "about" section of this subreddit. It's full of people who stutters from all around the world and we're all really friendly, feel free ro check it out if you want. I wish you a good day/evening/night my friend
