I can't say I'm no longer struggling with the negative effects of my stutter but I guess I've made pretty good progress in the self-acceptance department these last few years. Here are a few things that help: 1. Figure out more about yourself that isn't your stutter. What you're good at, what you like, what you're passionate about, etc. Knowing that you have your own strengths and identity outside stuttering really helps with confidence. 2. Find a circle of people that you can talk to, that you know for sure don't mind your stutter. Friends, family, whatever. 3. This may sound cliche but really try to get out of your comfort zone. Go to new places, try new things, meet new people. It really helps desensitize you towards uncomfortable situations. Admittedly, my stutter still gets the best of me sometimes so whatever you do, it will still suck to some extent. But that's life and life also often sucks for non-stutterers.
