I completely understand you. It sucks. It sucks. It sucks!!!!!!!! I failed many job interviews because I am stuttering. I was able to get to the top master program just because that didn't have an interview, but now I can not even contribute to the class because I can not convey my speech as a normal person. I just want to shut up and never raise my hand to give an opinion in my class. This shit doesn't happen when I speak with classmates or friends, but whenever I speak to many people ... I just want to die.
