I’m 35 m who stutters Honestly the best mindset you can have is “fuck it”. Once you stop caring what other people think your stutter won’t even be on your mind. Trust me I get it..I’ve had to dumb myself down, work dead end jobs, no social events etc etc. I was the guy at work/school when it was my time to speak I would act like I had to go to the bathroom, act like my nose was bleeding etc lol. TRUST ME I GET IT I just started to look at it as if god put this obstacle in front of me to see if I would conquer it or give up. It’s people out here with no limbs, blind, def and we give up over a speech impediment? Again once you stop caring what people think life will be so much easier. Some will laugh at you, some will befriend you and some won’t even care. Speech therapy doesn’t work for everybody. Everybody is different, but you have to put the work in. For me rapping/singing helps me alot. Also changing my voice tone to make it deeper. I’m in aviation school right now and I change my voice on the radio communications all the time. Just play with your voice and see what works for you. Don’t give up
