I would argue that Oxford being her lifelong dream and her being miserable there aren't mutaully exclusive, especially if she's on a course that she doens't enjoy/if different to how she thought it was going to be. I imagine postgrad at Oxford is tough, and I can't fault her for not enjoying it as much as she thought she would.
That being said, applying for a masters in what you're not fully interested in is baffling to me. I was looking at masters courses today and they seem so intense (and expensive), I can't imagine going in without a genuine passion for it.
I think Ruby would come across as far more genuine if she was honest about how she was finding Oxford. I know people sometimes tit on Eve Bennett, but the way she talked about her uni experience was very well done in my opinion. Oxford is difficult and it can be isolating, even when you're surrounded by people and things to do. I'm not saying Ruby needs to deep dive on her feelings, but highlighting the good and bad parts would probably be better content, and better for her mentally. If she is struggling, which borderline every undergrad in Oxford is, so very likely she is too, it would feel far better to talk about it that to keep up a persona online knowing that it doesn't reflect how she really feels.
I imagine that beneath it all, Ruby is a very sweet, intelligent, ambitious young woman who would genuinly benefit from sitting down and working out what her aims are in life and how she plans on making them happen. Oxford has the potential to do wonders for her outlook on life, her confidence in herself and generally how she matures into adulthood, and I really hope it does.
