My sister is 24. As a child she was a very dramatic person, loved being centre of attention and the conversation and I never minded as I was always a quiet child (I'm older, I'm 28). I've changed a few details so it's not totally indentifiable.
But as she got older this turned to lying. She lies about everything, even small things- and my parents always have made excuses that she would grow out of it.
She would lie a lot as child. She would tell her school friends she has 3 brothers (she doesnt, just me her sister). She told them we had a dog, we didn't. She told them she had been on holiday to certain places when she hadn't. It was pretty harmless in the grand scheme of things at that time- but did cost her a few friends.
But now she is 24, and is still lying constantly. Told work friends that she was going to America on holiday but actually was coming with us to spain. We weren't allowed to post any photos encase they found out. When she found out her boyfriend might break up with her, she told him she was pregnant- and then told him she miscarried and emotionally convinced him to stay. She admitted to me it wasn't true.
Every time she gets found out or one of her lies get unravelled, she'll leave her job, or relationship or ditch the friend that found out and then as her family we have to pick up her mental health for months on end. She just told another lie in her job that she can't work an upcoming saturday due to a family wedding- there is no wedding and now for months she'll be scared of getting found out rather than just saying she can't work.
She also constantly threats suicide- and if someone finds out she's lied, or threatens to cut her off- she will immediately threaten suicide. She's offered counselling each time but never sees it through. I'm just exhausted from it. Not only can I never believe a word she says, but nobody seems to pull her up on it. My parents have a sort of 'what can you do' attitude and she goes through friends so quickly none of them do. I've even asked her before why she lies so much and she'll say ''I don't know why I do it''.
The worse thing is- is there's zero reason for her to be like this. She is a lovely girl (really), she's successful and got a great career in advertising, on great money and owns her own home. There's no reason for her to pretend or lie. Gah! I'm just at my wits end I guess and wondered if anyone has any advice.
