Learning to breathe properly helped me a lot, but more importantly learning to accept my stutter rather than hating myself forever. Don’t let your stutter stop you from achieving your goals, I stuttered my whole life. Although I’m only 26 and have a long way to go. I only started to really work on my speech when I was 21 and wish I did so sooner, I still stutter but not nearly as much as I used to. Most of us will probably never be 100% cured but you can get damn close. My dms are always open if you’d like to chat or even a call if you’d like to work on your speech :)
