Accept the idea that you'll have to live with it for the rest of your life and accept that is not as big of a deal as you think it is. I have it since I was born. I'm 22 now. It was difficult along the way and I did find obstacles, but everyone does, even non-stutter people. Every one fights his own battle, I feel lucky to have a stutter instead of something worse. Relying on a miracolous cure will only lead you to a false feeling of hope.
