For ages I've avoided speaking because I knew I will stutter but for some reason for the past 3 weeks I just didn't care anymore about my stutter, it held me back mentally way more then physically I just decided to speak without thinking about if I will or will not stutter, it really helped me, I felt way more confident. Start slow. Ill be honest I really think after all that time with the mindset that my stutter is caused by anxiety and it is psychological and not a physical thing it really became what I thought it was. I still stutter sometimes but it's not like it was before. I am lucky I'm aware that I am. But man it really does starts in your head, be confident love yourself work hard on your social skills, have faith brother even if you will keep stuttering you will feel much better, it will do good for your soul. And if you take a moment to think about it, it really makes sense. Imagine that for half of your life you constantly think and shove it down to your own throat that you stutter, that you can't speak around people and that this is how you are supposed to live your life. I did for 8 years do you understand what it does to a person, you code your own mind to act a certain way that will suit you stutter you hold yourself back. This changes you completely you are not you, you are your stutter. Don't live like that, it is a waste of your life. Meditate, try to achieve peace with yourself, be whole with who you are. I believe in you, I'm on my way as well, uncertain but trying.
