I can't feel bad for her because she's just so damn privileged. She's depressed? Ok, she has the time, money, and ability to go to therapy and sort herself out. She's unfulfilled? She has the time, money, and access to career coaches to sort herself out. She's bored? She has the time and money to do/go/learn literally WHATEVER she wants. She wants to be a chef? A designer? A florist? She could do all these things. She wants to learn astrophysics? Unlikely but if she fancied it, she could. This "career" of her gives her so much money and free time that she could turn into opportunities and even into content. But she chooses to remain the same, shallow, boring person.
She's obviously struggling mentally but there's absolutely nothing keeping her from seeking help and moving past this. Most people would love to have all the chances and opportunities she squanders.
