My dad (not biological) used to say it was his fault, although I doubt it. He didn't come into my life until I was 3 or 4. He was the first person to discipline me so I was scared of him and nervous. I didn't start to stutter until he came into my life I think. But i should have been diagnosed with tourettes too bc tics like clearing throat or nodding head nonstop would accompany the blocks and stuttering that were uncontrollable and still somewhat present 30 years later. Something wrong with my brain long story short.
