I think first step is finding a support group in your area. And then from there find a speech therapist with the specific goal of effortless stuttering. I say find a support group first because it’s usually free and the best therapist IMO on the ones that are recommended to you by people who’ve been helped by them. I think you might find some comfort in this podcast that I recommend a lot. https://stutterrockstar.com/2023/03/15/living-not-surviving-episode-254/
