My daughter is a pathological liar and it's killing me

I am at my breaking point.<br><br>My daughter is 13 years old. Ever since she was little, she has lied about EVERYTHING. I mean if she is eating cereal for breakfast, and you ask her if she likes the cereal, she will say she hates it. If you say okay, then you won't eat it anymore, she will say she was just joking, she likes it. She will deny she said something when she literally just said it. And it goes on and on.<br><br>I have been to my wits end so many times with this, and have tried everything. It's so hard to describe, but the only thing I can compare it to is being in a cult. Where the leader says "this is up" and this is down. Then randomly they say "this is down, and that is up". You know what I mean. And you can point out what they said last week, and they will just make fun of you for even questioning them. That's what it's like living with my daughter.<br><br>Things have gotten worse lately, because now she is getting in trouble at school for lying. And she will deny that she lied. Then she will say the teacher is a liar. Then she will say the teacher bullied her, and is picking on her, and that is why she got in trouble.<br><br>I am fucking exhausted. I just want to die. Last night was the breaking point. My wife was telling my daughter what she did wrong, and she was denying everything. So my wife said let's go to my room and talk about this, and my daughter said fuck off. My wife said what did you say, and my daughter said she was just joking, she didn't mean it. Then my wife started talking again, and my daughter interrupted my wife and said "I'm not crazy you know, you are the one who is crazy", and then she started laughing like a maniac. <br><br>I have never felt so helpless in my life. I just feel like giving up. I'm 46, I don't have the energy to even care anymore. My daughter is becoming more and more of a bratty entitled piece of shit every day, and I don't know how to stop it. I have read books and watched videos about how to handle this, but I just don't have the energy to care anymore.<br><br>I just want to die.
