Does anybody here struggle with C's?

Does anybody here struggle with C's? I can never seem to get my C's right no matter how hard I try it's just ca...ca..can't and munch... munch munchkins it's so frustrating all my friends at school correct me, but I know I can say these words but I can't get it out it's just infuriating and people ask why I do this and why I only do it sometimes and not all the time and I never know what to say... I just posted here to get some answers about why i might do this and to make myself feel better... If you are reading this.. Thank you. 🙃
