But also, in my experience, some of the problem is also the attitude schools have towards this, which tells me they’re not trained enough to deal with the variety of mental and social issues kids face nowadays.

How could they be? Things began changing so quickly from the 2010s onward and it’s taken society at least this long (some are very much still in denial) to realise that children having 24/7, unsupervised access to the internet (and the technology it is intertwined with) is an extremely bad thing for their development. It’s such a difficult situation because it requires swift action, but it’s also not long ago that we were being told that children growing up as “digital natives” was a positive thing.
