I feel you and it really sucks. I'm sorry. I have experienced the same growing up and it isn't fun In my experience, the harder you don't accept it or fight it the worse the stutter is. Once I accepted and stopped caring about my stutter the better it got. I still stutter but it's not as bad. But I do still havey bad days. Still go to speech therapy and practice. Like another commenter said try going to therapy or a doctor to find out why you randomly got it. Good luck and keep your head up
