First thing you have to do is change that point of view. It's unlikely that it will go away, it can lighten up a bit during the years as your confidence boosts up, but thats it; very rare to just disappear on its own. So you have to drop the objective you set of "i want it to go away, fuck this shit" and replace it with the will to accept your stutter and live as happily as you can with it. It's the hardest part of it all, accepting it. We tend to hide it and stay silent but that's just like running away. Not everyone cares that you stutter, not everyone is a dickhead, most people don't care and they have their own problems, so just live your life. Force yourself to stutter on certain situations, get out of your comfort zone; i started doing it months ago and i really changed confidence wise.
