Help

Help Hi everyone! My aunt, who I do not let along with, is coming to visit my parents for about two weeks. Every time she stays, my stutter becomes worse. So I end up not speaking to anyone while she is in town. My parents do not want to understand why I am super short with the conversation. I only give out one-word responses. I have tried to explain the situation to my mother and father, but they don't understand where I am coming from and call me rude.
