I think Lauren is a tad bitter that she wasn't the break-out star of TOWIE that she thought she'd be. But the problem is that she's just so unlikeable! She wasn't funny like Amy Childs, she wasn't warm and relatable like Sam and Billie, she wasn't quirky like Lydia, she wasn't gorgeous like Lucy, etc.. She was so awkward and vacuous. She served no other purpose than to be Mark Wright's doormat. At one point she was trying to shop around an idea for a reality show revolving around her and her sisters, like a British Kardashians, but thankfully no network was interested!
And speaking of MW (who I also find insufferable and cannot see the appeal whatsoever, seriously, can people please stop giving him jobs on TV/radio and stop inflating his already massive ego!) He treated her like garbage, but I think Lauren always thought that no matter how many girls he hooked up with, he would always come back to her (like he did for 10 years) So it really must have been gutting for her when he moved on and married MK, especially since MK is stunning and MW seems to treat her a million times better than he ever treated LG! MW's family are all arseholes as well, they're all riding his coat tails (remember Jess and her pop 'career'?
Why was every song about a dancefloor?!) and they seemed quite happy to discard LG as soon as MW did, it was clear that they thought she was beneath him and not fitting with his self-created image of 'The King Of Essex' (vomit
)
So yes, this plus all her family issues, are why LG is such a flaming dumpster fire of a person, but maybe if she spent as much time working on her self-esteem, or starting a business, taking some courses etc, as she does taking heavily filtered and edited photos of her huge fake arse, she would get somewhere in life! Money can buy you all the lip filler and Brazilian butt lifts you want, but you can't buy a decent personality!
