Hii! First of all, I totally know the feeling where you , yourself think there is something wrong with you and you are not normal but YOU ARE TOTALLY NORMAL. There will be people who probably think that they are better than us cause they dont stutter but mostly its rlly in our head, I myself think that i am not good enough or like not normal, but thats cause of the trauma and rlly bad “treatment” I received. U are totally fine, your enough, i believe none of you coworkers think less of you♥️
