I know what you are going throught i an 24m Stutterer and i am going through exact same thing, It's a daily challenge we have to go throught it everyday, every second, but try to not let it put you down or it should not be negative,i too get overwhelmed everyday and thinks that living with a Stutterer and not being able to express myself, and still there will be no hope of improvement, I understand bro it's a lot at the end of the day we all are living life in hard mode that's the truth i have to accept everyday i wake up because that will be my realty, but i don't let it bring me down, i know it's the hardest thing to do and i still struggle with it everyday, we have to accept our truth and reality and live accordingly, Right now i am focusing on just being happy regardless of stutter or not and this itself is hardest when there are 100 things that will bring you down, just being happy and present is a challenge.I hope you also find that, If you want to talk more dm me
