I have fluent days, sone completely fluent days. But I'd never say I'm cured. It's there, whether I manage it or not it still exists and is a part of my identity. I appreciate you reaching out to help people but please stress you aren't a professional. Your approach is quite like the Maguire Program which I took when I was 17 a long time ago, I then went on to get a drama degree, act on stage and tackled it head on. There was no cure though, that implies you have a disease, which you don't. Accepting it isn't something you cure but something you own personally, something you care for and tend to and make something positive. My childhood severe stutter is my spine. Peace
