Is my teen a Pathalogical liar?

My 15 Year old daughter has told extreme stories since she was very young. A good imagination is nothing to worry about but, her stories are based on a victim mentality. At 3 she was an orphan and her parents burnt in a fire, I, here mother was standing next to her when she told this. I know that young children aren't believable liars. As she got older her stories became more complex. She has been an avid reader and is very intelligent. I have been a vigilant mother and have been very strict with her for fear that it is too easy for her to get in trouble. Her father was Bi-polar among other things. Recently, her stories are getting worse and Im afraid she could put her family in jeopardy. last year she was texting a boy out of state telling him she had a violent boyfriend that was beating her up and she was still spitting blood from him kicking her in the ribs, I caught her and txted this poor boy who was freaking out for her and ready to send the police to my house and told him she didn't even have a boyfriend. Last month she told a preacher that she is always alone with her brothers and I get drunk and beat her. I was devastated to hear her claims as I had to speak to child services. She said she was very sorry and that the preacher had lied and she hadn't said all of those things. while her stories make her a victim, it is others who are becoming victimized. I don't know how far this will go or what I can do. I am uncomfortable with councilors been through that with my ex. I am very uncomfortable with prescriptions, my children have never been on any and I feel the purposes of them have been lost due to the profits they generate.
