I don't know how much worth your stutter problem and what issue you face but think I know pls Try to make separate your personal issue or professional issue with your stutter. I know it's really difficult because communication with others is a basic thing but tried it. ​ I also had a stuttering problem since I was 6 years old (now I am 23 years old and last year in my college) and only stutter lips also. so I sound lots of work wrong which make my condition really worth. even somehow I can make my speech fluent but I make my word wrong(pronounce) something like CAR to TAR, JOKER to DOKER. you can say that in 27 (English alphabet) my 6 are wrong and Hindi the number is near to 10 and its really big number. and the problem is really big but you also speak the wrong word due to this I lost every campus placement but some how I can able to get one which package is lowest but I know my skill is really good (to get the 3x) ​ After everything, this happened you my story but just listen(until now I didn't go to any therapist and for not going to a therapist i really regret now because my last 6 months totally free due to covid) After everything, this happens I decided to go to a therapist, and luckily he was a really good therapist I found in my city until I completed my 20 sessions and just believe my 80 problems are solved and my **lisp** issue is almost fixed within 25 days (which I suffer from my whole life loss my all confident, and made me looser just like you might see in anime or tv series). but now I can clearly say that if I continue my session nearly 1 month more I might fix my stutter and lisp problem. ​ And one thing which I want to share with you that my therapist told me first just focus on **lisping** and forget about stuttering once you master with a lisp like now(and able to make a clear sound with no mistake) then we discuss your strutting initially I think it's mad but once I master my lisp its automatically solve my 30% stuttering problem. and second advice for stuttering related (where I currently lie) tried to maintain a flow until you can able to maintain your flow know one can stop you. ​ Note: one thing which I want to share with you is if I think your therapist is not professional or his therapy didn't work on you so just look at some others who have more experience. And thrid to find the core reason why you stutter. (in my case I also think about my lisp: is I told its current, what is a told something wrong). ​ I Hope this will help you.
