I’m going to take the opposite route here and say it’s ok to hate it. Acceptance doesn’t meant you love it and welcome it. Acceptance just means you acknowledge it’s an aspect of your life. I don’t like it either but I don’t let it get in the way of things I care about. As for good things that come from it, I’ve found a community of people that I love hanging around that I wouldn’t have if I didn’t stutter. It’s taught me to be more mindful of how I communicate with others and how to listen when someone else speaks. It’s given me opportunities to grow as a person in ways that I wouldn’t have had otherwise. It’s given opportunities to help other people because I can relate better to them and given an outlet for someone to feel connected or supported. There can be a lot of bad things I focus on regarding stuttering or literally anything else in my life. I choose not to. It’s not much different than any other frustrating or irritating thing that’s apart of our life. You do stutter but that doesn’t mean stuttering is the entirety of your personality or identity.
