Stammering since I was concious.

Stammering since I was concious. I'm 24 now, I'm able to control a bit of it. But being excited, anxious, or any impulse emotion i stutter. But, I do not stutter when I'm alone, never. Researched alot of neuro, SLPs. Any technique, I do it for few weeks and when I stop using those, it's back again. Give me the mindset or how does this really work. Thanks. 🙏
