I’ve gone through the same things you mentioned above. I’m 38 yrs old so faced more than a double of this negative dark phase. People say I should’ve accepted it. I smile, laugh & cry of anger at the same time. Recently I found out that cleaning ur GUT can dramatically reduce ur stuttering. Cleanse ur colon & liver. I Know this sounds weird & unrelated but I promise you colon & body that is full of bacteria/parasites/fungi etc >> aka dirt and outside of a body that is covered by dirt >> bad orders (sweaty dirty underwears) + (mouth) + down there &&&& ur hair ) add to that ur childhood traumaZzzz , all of these factors are a magnet of dark spirits which lives in you and was the ROOT CAUSE of our stuttering. Full stop. They go like it’s caused by chemicals in the brain 🧠 I won’t say this is BS however ill go (what has caused these FA chemicals in our brains?) >> root cause 👆 Cleanse ur inside, even ur muscles will be relaxed & that could eliminate ur stuttering. There’s hope. I know it hurts. I f know. I lost many valuable people /thing’s because of stuttering. If I could do you can do it. A bright future is ahead. Under this pressure & weight We are diamonds taking shape 💎
