For me, I think accepting stuttering is like saying "I don't care about stuttering anymore", "stuttering is neither bad nor good, it just is" or "I will not try to hide stuttering, fuck it. I give up hiding it and I just don't care" but also continue striving to improve it, continue training the techniques every single day and researching about ways to solve it. Imagine a fat guy who goes to the gym and wants to get fit, but he uses baggy clothes trying to hide his body because she is ashamed of it. And the baggy clothes make him feel uncomfortable, he sweats a lot and he doesn't like the style of the clothes. But one day he just says, fuck it, I don't care if people think I'm fat, I'm not going to hide my body anymore. And starts to use regular clothes and feels way more comfortable, but at the same time doesn't stop trying to improve his body every day. I mean, that was a pretty bad example, but, what I'm trying to say is that accepting doesn't mean giving up. You can accept your stutter and still strive every day to improve it. I think accepting is just to lower the pressure and fear of stuttering. As Order\_a\_pizza said, try to learn about CBT and/or stoicism, these things can help you on accepting stuttering. It's a hard road, I'm still trying to accept my stutter as well. It's not easy, but hard is not impossible. Trust your endeavor and your discipline, my friend, we're all going to make it.
