Truer words have not been spoken. Seriously.I think the worst thing to happen to her was making so much money so quickly. Her anxiety will no doubt have worsened because she had the means to avoid anything that may have forced her to confront it, like having a job. She never had to work hard to save up for something out of her reach, she never needed to keep going because stopping would mean she couldn't live, she doesn't have to be motivated because she can quite comfortably do nothing. She's also never had to make compromises in a team because she gets things her own way, she never had to work under a boss and do what someone else tells you to and have to deal with it just because....So many character building experiences.
And this is not to diminish the fact that she may very well experience anxiety which can be quite debilitating. But the fact is, unlike most people who suffer from anxiety (myself included), she never had to push herself to do things outside of her comfort zone simply because she doesn't have to. I agree with everyone posting about how there is quite literally so much she could be doing with the opportunities she has at hand (fashion, home decor/renovation etc)... yet she simply does tit ALL, because she's loaded and can't be bothered. Anxiety isn't just the sole reason for this, it's laziness and lack of drive because to her she's already done enough and made her "millions." And I'm sure her sticking with Alfie is also related to this.
