1000% YES, go to speech therapy. I didn't get fluent until my 20's. I was a severe stutterer from my earliest memory. Severe, as in, never a fluent sentence. Blocks so bad that I ran out of air. I knew I would always stutter. The blocks grew from a 'simple' stutter to jaw-locked blocks that would last until I ran out of breath. The public school I went to had me see a speech therapist once a week during school. It wasn't helpful. I went to see a professional speech therapist in my mid teens. It didn't help much. But that's on me. I didn't put in the work. When I returned to the same therapist in my 20's, I made significant and rapid improvement. For me, it was about putting in the time and effort. Like going to the gym or learning an instrument. If you only work out with the trainer once a week, or only play during your lesson, you won't improve. Fluency is a lot like that. You have to work at it. Putting in less than a year of work has given me over 20 years of fluency. I'm not without blocks, but I am mostly fluent. Most of the people I work with take months to years before they realize I have a stutter. These are people I talk to every day. In my time in this subreddit, I am gathering that there is a world of difference when it comes to speech therapists. I will always advocate for speech therapy. And for doing the work to achieve fluency.
