Well done on your progress. The only way is up. Filler words for the most part aren't the answer, but progress nonetheless. Ideally you would get to a point where you don't need filler words, voluntarily stutter and be happy and content with who you and your speech are, incidentally making your speech better! Come join https://stutter-connect.com/ to practice speaking with other people who stutter. It's free. You have nothing to lose!
