Don't panic and overthink. You only feed a stuttering mindset by doing this. I know that it's easier said than done. I had blocks on my name and it went away after a few successful introductions because I never viewed myself as a stutterer. (advice I found on the internet) I'm 37 years old male, and I developed stuttering during puberty which became worst and worst with each passing year. The reason for the stuttering was purely psychological, I was really depressed with the lowest of self-esteems and the stuttering was the cherry on the top of my miserable cake. I didn't feel comfortable around people, very shy, every time I had to speak to someone I started mumbling or couldn't take a single word of my mouth - like I hadn't enough air in my lungs. However, since last year that changed, I got fed up with the situation. I focused on my personal development, mentally and physically. The more my self esteem increased, the more stuttering decreased. At this moment I can proudly say that I can't even remember when was the last time I stuttered. It just disappeared, as simple as that. Once I got my confidence, I stopped worrying how people see me, and when I'm about to speak to someone I just block the thought of eventual stutter. You all know how is the feeling to be non stop terrified of the way you'll talk to someone, and the more you think about it, the more it gets scary. Of course, I guess that doesn't apply to everyone, but try it if you can. Focus on yourself, try to create the best version of yourself and that might boost your confidence. It's a chain reaction you know, one positive thing leads to another.
