There's nothing to be healed. The idea that it's an illness is a faulty premise. The best analogy is that it's a software problem, not a hardware (medical) problem. This is supported by the fact that many PWD have fluctuating levels of fluency. Some are perfectly fluent when alone. Some of us have good days and bad days. Our fluency changes over time. Our stutter isn't consistent. It develops and changes over time. You're never going to have a fluency pill. No more than you're going to have a love potion. It's a fantasy. But what you can do is seek out and find effective fluency therapy. No one is born with a stutter. At some point the stutter developed along with your speech. It's possible to learn to speak fluently.
