Perfectionism. That hit a sore spot. I never went to therapy but my mum was an English tutor, and she. Noticed it when I was quite young (maybe 2 years old) and immediately started taking measures like making me practice tongue twisters. It think it worked because up until 7-9 years old when I noticed i was “developing a stutter” everyone who knew me as a kid said I’ve always had a stutter. But I grew up with very high standards.
