OK...so fill in the blanks. Why is she angry that you don't want to go ? What are her concerns about you staying home ? Have you had an adult conversation with her about it, in a mature rational manner to find out any of these things ?
I would open up a conversation with her to find out. You have to do it in a calm, reasonable manner. (no teenage eye-rolling etc....lol) Listen to her and then... as calmly as you listened, you tell her your side.
