No, she is miserable because she has no focus and no discipline.
She has led an extremely privileged life, one that enabled her to jump on the YouTube bandwagon at the right time - she had disposable income, lived in a prime London location, in a house with enough rooms/garden for filming opportunities and her parents travelled a lot so she always had the latest covetable only-available-in-France/USA product etc, enough money for hauls, always out and about in London, money to eat out all the time, so lots to vlog etc.
She found making money easy and always just did enough to do well in that regard. She never set herself any real challenges that needed long term discipline to execute and tended to give up easily (eg even regular blog posts were too much for her). While her peers spent their late 20s developing themselves, Lily coasted and now doesn’t have a lot to show for it (other than financially). She now suffers from a lack of focus, is drifting and has never practised the discipline to get herself back on track. Having a baby is never going to improve the fundamental things wrong in your life.
