Bro i have the same condition and ykw I have tried speech therapist two times, one in my childhood and one recently but it's still the same and now it's been killing me from inside day by day. Idk what to do, I've tried every method on YouTube, every technique, every suggestion i could get but i didn't worked. I can't even say my name without stutter or even the simplest thing like ask for goods on the shop. At this point I've just accepted it as a part of me fr. People just make fun on my back and what can I do about it anyway, so I just cut connections with them and just don't care. It is a curse bruhhh living with this, i just can't say what i want to say. 🥀
