Living with a narcissistic paranoid mom?

I recently decided that my mother has Narcissistic personality disorder, and she has it BAD. She believes she's psychic (and one of the most powerful psychics in the world, mind you) while claiming to be morally superior to most others, saying she's on this 5th level of ascension out of 7 for becoming enlightened and morally better than all of us. Now that may seem alright to have a religious belief, and I think it's alright too, except for the fact that she is in NO way close to being on this level of peace that she claims. She thinks the NSA is after her because she knows too much and is "smarter than them." She thinks any problem at all is the NSA or some kind of hacking or a result of my "crazy" (not really crazy) dad. I describe her as a woman full of rage. She repeats over and over she has multiple personalities which I believe, but she also exaggerates any ailments of hers, and makes her children handle all her problems for her: calling doctors, attorneys, THE NSA and relatives. She blames many of her problems on me, constantly boasts, ridicules that I have Asperger's and thinks I have all these problems that I don't have then blames it on them. She GASLIGHTS EVERYONE. She lies and sometimes believes her lies. She overreacts. What do I do. I'm 15 years old still and have a 12 year old sister. I haven't been able to maintain any long relationship because of this too. Constantly cancelling plans, constantly under persecution. She thinks she's one of the only normal ones.
