My daughter is a cronic liar, please help me!

How old is she, what sort of things does she lie about, does she lie to everyone, or more to you?

A lot more details

I know what it's like to live with a chronic liar, my biological mother is one... Her's however went along with being bi-polar and a lot of other disorders. I believe it has nothing to do with the parents (I now live with them). As time has played out, you just simply have to catch her in the lie and confront her, she may not even realize she's doing it.

How old is she? Chronic liars are different kinds, one knows he is lying to avoid or gain something, another has distorted thinking and then believe his lies it is like: lie then believe it happened. Another is exaggerating in what he says.
In summary it is a personality disorder(not bipolar definitely bipolar is a biological disorder and has no much control over his action or thought) they lie to everyone even to themselves
The bad news is one of the caretaker is also like her
The good news it can improve and may be cured with a lot of pain
