I had a friend that stuttered on vowels, I wish I could talk to him again but I left the discord, it was kind of a swamp that was very bitter (like all social media) and walking out for the 3rd time (after pausing multiple times before) felt so liberating, it was like walking out of a swamp literally and stepping into the sunlight free from all that bitter hate and judgement underneath. But if you ever go on there or are on there, they may still be someone from Maldova that tried this and we spoke a lot about it and he had very positive results. Doesn't matter if it's vowels, names, different locations, all the same, don't dwell on it after and if you'd like, you can try this along the way that helped me in conjunction with the mindset. It is something I shared in chats with others, a few more concepts to keep my energy and not feel so drained and out of breath as I began: I told myself not to dwell on it no matter what, it was an all or nothing endeavor. Sometimes it still felt impossible but rather than lose all my energy i tried repetition when i could. I would be stunned when that worked, basically i was just buying time, back tracking, letting go, resetting and if it didn't let go i didn't dwell on it either way. slowly the difficult things got easier and the nearly impossible things got difficult then easier and now i can care less and it's not on my mind. My stutter went from hard blocks, impossible to even talk on the phone to a little stutter here and there, same ol' back and forth now and then and move on like nothing happened. remind yourself to try the opposite of all you may be used to. rather than force, try to repeat and let off, rather than worry and rush, try to slow as you do it, almost like an entire change of pace, rather than dwell on it, don't even give it a second thought.
