Why does my mom bully me all the time?

my mom makes horrible comments to me all the time. For the past month, it has only gotten worse. I have a darker image, you see. I wear a lot of black, black make up, my hair is black, etc. Im a goth if you haven't already guessed. She says things like "Do you worship satan? You have a crucifix on your wall? Is it up side down? Do you think your a vampire?" etc.. What do I do? I cant stand it anymore.
