Stuttering Solution anxiety?

Stuttering Solution anxiety? I have seen success with my stutterering. I accept I'll never be fluent 100% but currently I'm 75-80% and the goal is 95% (1 every 20 words) Problem is there are dozens of "techniques" I've seen online and they are so overwhelming. I read them and think "What if I fail, what if this doesn't work for me, How did it work for them but not me, what if I exhaust all my options?". That anxiety and demotivating belief is primarily what can even cause some good rest techniques to fail for me from time to time. How do i have faith in the technique and get rid of the anxiety of the technique being fake or unsuitable for me?
