I think the idea of self therapy is a great idea. Practice and look for videos and do research on your own to try and find techniques. Then find a topic you want to know more about (like literally anything of interest) and just practice reading outloud to yourself. Practicing speaking with a stutter is super hard, but in my experience it helps you develop and practice techniques that can help you be smoother. It's not going to be easy but it is worth a try.
