I read the article and found the concept interesting.
I think a lot of mental illness is around not being able to be 'normal' in other people's eyes. There is so much more to learn about what is 'illness' ie a short or chronic condition that happens as a result of trauma or misalignment which can be treated or 'cured.' Or, a condition such as BPD mentioned here which isn't really an illness but just how people are, which cannot be treated but can be managed with the right approaches.
Psychiatry is the youngest of all medical sciences and massively under-appreciated and under-funded. There is so much mystique and mis-information around it's a wonder anyone gets helped.
However as you say this doesn't help these young people caught up in this.
My work before I retired was working with these young people; self-harm, depression, anxiety, anorexia, I came across them all.
One thing I learned was that what they needed was recognition and understanding, but not necessarily in the ways the other services were offering. They needed to know most of all that they were valued and indeed had something to offer others.
This was sometimes in direct contradiction to some agencies promoting that endless and fruitless search for 'identity,' the ego-based belief that they had a right to be how they were and the problem lay with others and not themselves.
So many young people are caught up in this maelstrom of confusion and anti-social thinking. It caused a lot of destructive and wrong thinking, often resulting in the opposite impact, causing deep seated anxiety and a lack of awareness of how they fitted into the world, and not the world fitting into them.
I don't know if this drama is good or bad, anything that raises awareness and promotes discussion like this can only be a positive thing?
I once had a student who really loved Alice in Wonderland and I decided to read the novel with her. She became quite bored with it because it wasn't what she thought it was. I think she had only seen the screen versions and thought the novel would just be a re-interpreation of those. We live in a cultural desert.
My impression is this drama may be so removed from Lewis Carroll it will be unrecognisable- the novel is very much about how Alice learns how to gain confidence in her emerging place in the world, and not expecting the world to put her in the centre of it.
