I think one must be careful about mental health and making comparisons (me included - I forget this all the time). It's really hard to see BB as a person struggling b/c of all the privilege she enjoys but I do think she is struggling. Being British but having spent most of my life in America I had to unlearn several very British barriers to good mental health. I grew up with the "but there are so many others worse off so buck up and shut up" attitude but therapists here have made me realize that my depression wasn't something that *should* or *should not* be the case, it just was.
In the same sense, I think BB is constantly at conflict with herself - "I feel this, but I shouldn't because I have all this work and things" and it comes out in a stream of consciousness whine that others do not relate to or makes them feel uncomfortable. And this creates a bit of a spiral downfall b/c the more she reveals the more STFU people become. That's the hard part about depression and anxiety and part of the reason people keep it silent. Because really, depressed or anxious people are irritating. I have had major depression on and off since I was a teen so I'm saying this from that standpoint. The more you are depressed, the more you withdraw, the more of a downer you are, the more awkward you are, which does not help.
So, in that sense, I feel really badly for her.
The problem is (I think) that she is trying to dig herself out in the wrong direction - tunneling downwards. I had to laugh when I saw that book about climate change and over consumerist woes of the world. So buy a pricey book to learn about consumerism? She also has a tendency to avoid and blame others for her woes.
Have a rethink about this whole direction with the help of an objective party like a therapist, good friend etc - instead of fixating on all the mean people and criticism? Being a fashion and *lifestyle* influencer is going to be a mental health minefield, at least on occasion, to all but the most hardy of vacuous individuals. Everyone on YouTube (and Patreon!) is going to have to figure out how to side step the dog doo that comes with it.
P.S. When talking about alterations, turn the bloody camera to portrait so we can see your whole body! Streuth! How difficult is that? For a "visual artist" especially?
