Not a doctor. But -I also had a stutter. I didn't have one as a kid but had it in middle and high school. It was so bad that I didn't wanna hang w my friends. I never raised my hand in class because I knew I literally would not be able to spit out the first word. Once it took me 10 full seconds to ask if I could use the bathroom and my teacher stared at me like I was stupid. Anyways, i am not sure if this is a coincidence or not, but after I started taking Zoloft, an antidepressant- my stutter got better. It's been a year since I started and I only stutter when I am talking really really fast. I am 10 times more confident. I also notice when I don't take my med I stutter some that day. Not sure if it'll help but just wanted to put in my 2cents because I know how difficult it is to have a stutter as an adult. It made me feel so hopeless. I also think it is tied to confidence levels- or so my therapist said so. I'm not sure how the medicine helped me but it did. Also- I worked as a host for 9 months so I would have to greet customers- which forced me to practice speaking first to someone-which was definitely a trigger for my stuttering. Maybe a combination of working and the meds helped? The job raised my confidence as well. I definitely did stutter with customers on certain words, but I would just have to improvise and say a different word and move on and forgive myself. But yea dude you aren't dumb stuttering is uncontrollable, people who don't stutter simply don't get it
