How can I ACTUALLY stop stuttering?

How can I ACTUALLY stop stuttering? I’m new to this sub. I’m 16 and have stuttered since I was 6, so for 10 years. From 6 to 7 years old I stuttered a little but it went away, but as of the age of 7, it stayed. And my type of stuttering is when I say something: my speech just gets blocked. I have tried everything: therapy, talking slower, relaxing, taking CBD, taking relaxation pills. What can actually help? I’m going to the doctor this week and I’ll discuss with him what I can do. Maybe he can prescribe me like a medication which relaxes my muscles. Because for me that’s what it is: my muscles are very tight all the time. Anyone know how I can ACTUALLY get rid of it? I’m so done with it!
