I used to pronounce my hard K sounds like a T sound, I went to speech therapy at school and also dealt with the same issues with the “intellectual disability “ thing in early grade school. I eventually overcame the K sounds and I feel that going to speech therapy for the sound in particular I think tricked my brain in to believe that was normal okay to repeat the first syllable over and over. Then when people started to give me weird looks for having a stutter I was probably 8, and honestly a lot of people did give crap for it, but if I had to tell my 8 year old self one piece of advice it would be to let people know that you stutter, let them know what’s going on there’s no need to be embarrassed for being yourself. The harder I tried to hide my stutter usually is when I stuttered the hardiest. But when I let people know ahead of time that I have a stutter there is literally a huge weight lifted off my shoulders. I still fumble but atleast people know what’s going on👍🏽
