I have a stutter. Its slight nowadays and it comes and goes but as a kid it was much worse. For some reason being around my parents made it a lot worse while not as bad at school or around friends but still noticable but answering the phone was the worst. Some times I couldn't get a single word out. Not even a squeak or a sound and to this day I'm scared of a swearing the phone. It gives me really bad anxiety just hearing it ring
