Just re- read Richard's OP and he gives a very good summary of the sort of Govt. failure ( disinterest/malice?) which has led to a dearth of proper support for people in crisis, as well as being very open about battling his own demons.
I make no apology for commenting here, that one of very few services which was deliberately designed to have contact with every young person, was the former Careers Service. A service which was ideally placed to identify issues faced by young people as they stepped out into the big scary world. I'm not trying to claim that the CS was the 'main' provider of mental health support etc, but it was a significant link in a web of interlocking support. Whilst not something that was shouted about.. referal to and liaison with appropriate specialist support.. (social services, housing, health, etc.,etc.) where it existed, was a routine part of our work.
Sadly the Careers Service in that form was disposed of by Blunkett almost 20 years ago and replaced with the 'Connexions' service. Under 'Connexions', the wider 'support' role.. beyond 'mere' Careers Guidance, was more strongly emphasised, though with little acknowledgement of what had already existed without the 'help' of Blunkett. Sadly, Blunkett's approach caused much confusion, including duplication of some provision and complete loss of other.
Finally, rather than listen to the professionals and experts, Gove basically dismantled anything resembling a national and consistent support system for young people.. under any branding or banner.
It's all gone.
Which is why it is so important to support those who have stepped into the breach.
