I think that you are able to speak more fluent than you believe. It is a neurological condition of course, but it's also a lot in the mind. You are probably thinking about it too much, which for all stutterers makes it worse. Try reading out loud by your self, and see for yourself that you can actually speak fluent. Also, sing. Then you might come to the realization that you don't "have to" stutter as much as you do right now. Try it!
