I worked on acceptance for a very long time before I truly accepted my stutter... over 10 years. As you are well aware we grow up and negative thinking patterns are ingrained in us and very hard to reverse. For me, the turning point was not only accepting your stutter, but also accepting all the emotions that you have with your stuttering. For me it was fear. I was totally ignorant of how much fear was still inside me and how much it prevented me... even though I was constantly going out of my comfort zone. I think after acceptance of the stuttering we still have these residual emotions lurking within us that need to be addressed. I realized that fear is so crazy, that it predicts your future. It tries to protect you from the trauma that has scarred your life. Once I acknowledged my fear, my stuttering acceptance was more tangible and usable. I suggest you find out what underlying emotions you have and work on those. And one more thing... remind yourself that most people are self absorbed lol and they really don't care about you stuttering on some words.
