I have to agree with @vio. From the moment I first watched her, I had an impression that she is a girl who is trying to be and to come across as someone much more intelligent and talented than she really is. Which isn't necessarely a bad thing, but you can notice that she has a really low self esteem and she struggles to sustain this image she created about herself. I mean just the concept of having a youtube chanel where you brag about studying 10+ hours a day, getting perfectly styled every day, denying being privileged although it's clear that she is (bear in mind how expensive the application process is - even if her studies were fully funded, an average German family wouldn't be able to even pay for all the applications), it's not what really gifted young people do. I find her really immature too, her opinions and tastes are very mainstream, she neither has real, deep passions nor common sense (which also makes me think she grew up very rich and sheltered). I'm actually really sorry for this girl, even before she announced she had a depression, I suspected she would burn out very soon. I hope she will find her place in the world and someone who will love her for who she really is one day and that she will understand that life isn't about prooving to everyone that you are the most perfect person in the world. I'm really sorry for sounding harsh, but as a girl who has also been labeled as highly gifted from a young age and who had a stage in life when I was a bit like Elena, I feel really bad about her and the toxic philosophy of life she spreads.
