Wow, you must be her hero, Yana. I know this is frustrating but may I suggest a different spin; you may be falling for her diabolical plan by focusing on her too much. Some people need negative attention to thrive. Inadvertently, you’re promoting her profile, giving her more exposure. Ask yourself what you’re really losing by her actions. Use her as inspiration to reach higher. Choose to feel good about someone desiring to copy your style. You must be doing something right girl. At some point, she’ll melt away like the wicked witch in the Wizard of Oz. Just my two cents.
