Has anyone found meaningful improvement with use of psilocybin?

Has anyone found meaningful improvement with use of psilocybin? I am going to try this out but wanted to get advice beforehand. For context, I highly believe my stutter is anxiety fueled and not neurogenic, what makes me say this is the following criteria: I don’t stutter when I am alone ( leading me to believe I get anxious when speaking to people and therefore stutter ). Another reason being I have times I am totally fluent but then times I stutter for 4-5 seconds on every single word. I don’t stutter when I do accents or impressions etcetera. I believe all of this means my stutter is early onset childhood fluency disorder and possibly is reversible due to that. I have found meaningful improvements at speech therapy for the last 2 years but the progress is quite slow. The reason I am considering mushrooms is due to reading the breakthrough benefits it has been shown to have on anxiety. As my own clinician in this I do think anxiety is the lead cause of my stuttering. I have worked out consistently for years, ate healthy, and basically striven for high goals in everything I’ve ever done. It just feels like my stutter barrs me from doing certain things I aspire to do in both my personal and professional career. I have about 4 grams right now and have never used it. Any meaningful advice you may provide to have a breakthrough in my fluency with the aim of diminishing my anxiety would be greatly appreciated thank you!
