Re: alter ego = schizophrenic??????
Of the schizophrenics I know, none of them have this compulsive lying. She definitely needs help. She could be a pathological liar, or she could have been delusional and actually believed what she was saying. If she really does have schizophrenia, then I doubt that the drug clonazepam (klonopin) would be the only one used. Klonopin is a benzodiazepine, meaning it reduces anxiety, and really doesn't help schizophrenia very much at all. I'm on it, but I take something else for my schiz. A doctor would most likely prescribe an antipsychotic.
I don't know if you can trust her.
She might have thought you wouldn't like her if she told the truth. If she had a traumatic childhood, she might have wanted to create an alter ego.
