I can’t control mine. Mine is a strange one because I’m not bad around my friends but I really struggle speaking to my parents and strangers. So I’d say it’s moderate. I can’t control mine, I don’t think I ever will. I spent the half of last year in depression because of my new job and one day it clicked. I realized that I can stop it, I can’t control it. So why should I bother being frustrated and down when I can’t do anything to improve it. I stopped worrying about it last June/July and I’ve been doing pretty well mentally. No depression, no negative thoughts. Another thing I used to do was compare myself to others with stutters. You are not them, your brain and your stutter is not the same as theirs. Stop comparing and accept that you’re going to have your stutter for the rest of your life. Sounds really harsh, but I found that once I engrained this into my brain, it made my speech better. Bit ironic lol
