During the time I was a target, I used to read narcissistic abuse forums. These were very helpful, because they served as a reality check. One of the features of female bullying is that you have no one to talk to. Even if it were a good idea to discuss this, it's not possible. First, it's not good to speak badly about another person, even if it's true.
Second, even if you did, no one would believe you. That's because female narcissists are sneaky. They abuse in a way that leaves no evidence. Almost everyone, with the exception of their current target, believes they are living saints. If you did happen to tell someone about their horrible, despicable behavior, most people would assume you're the problem, because you can't get along with this wonderful person.
This is why online forums can be so useful. Everything is anonymous and questions are answered by people who've been there. They'll believe you. (However, you should also be aware that disturbed people also haunt these forums, so be careful.)
But, once you've been abused, you should always be careful going forward. Even if you decide to seek therapy, you need to be aware that your therapist could also have some serious issues. There's a possibility that your therapist may also have a personality disorder, so make sure to keep your eyes open. If you see the telltale signs, make arrangements for an exit plan. If you aren't familiar with the symptoms of malignant narcissism, there's plenty of information available.
