One, you type like you're on acid, and you have no credentials to speak of. Two, let's say that you are completely right that stuttering is just brain chemistry. I personally think my own stutter is, because I stutter even if talking to myself. Your whole advice about "It's also important to mention that if you're isolated it doesn't help at all. Try to maintain a normal social life. For example, in my case, when I'm most active like going out, talking to people, and in that mood of facing the real world and talking to real people, that's when feel most fluid. That's logical, but many don't realize it."? That's completely irrelevant if it is all brain chemistry. You can't "good social life" your way into making brain chemical receptors operate normally. Whenever I see insane psuedoscience posts it just makes me sad that other stutterers have let themselves get this crazy instead of directly confronting their disability.
