Good luck buddy. I liked what you said at the end: "To become stutter free you can´t live like a person who stutter" It sound to simple to be true but for me, the simplier the better. It´s always the easier explanation the one that is true. There is no need to over think it. If you can talk fine when alone then you can talk fine with others. You just have to adapt yourself. Change your mentality. Dissolve the barrier that keep you out of fluency.
