Register Hi I'm from England. I have had a problem with stuttering for about 10 years. Every time I go to school and communicate with my friends it's quite hard sometimes. Even in class when I'm asked to read I'm always stopping after words because of my stutter. But the main thing is. I always have PE and every time the register is always taken I have to drink water so that I won't stutter or panic as my adrenaline is always rushing as my name is almost getting called in the register. Every time I'm always panicking in the PE changing rooms so please what should I do to try answer the register?
