Oh BTM, that's awful. What a way for that driver to behave - and your poor ds. And poor you. Yes to helmet and as much reflective/bright neon gear as possible. I hope his bruises will not be too sore tomorrow and the bike is fixable, but your poor nerves..
BD, I do hope that you are feeling better and getting to grips with making your decision. Your ds is clearly wise beyond his years.
Crem, that is fantastic news about you being on the mend. Have made note of Manuka honey just in case we ever need it here. I am about to go and read your links, so thank you in advance.
What can I say but "thank you".. You lot are a sight more helpful than the school. The HoY didn't get round to seeing dd today, although she said he passed her when she was on her way to lesson 6 - which is when he told me he would nab her. Obviously he had more important things to be doing. Don't know what to make of that, really, given what he said to me in the meeting this morning. 
I rang the GP this afternoon and was directed to ring the "Crisis worker" at Camhs. Which I duly did, only to be told that there were no crisis workers available today as they were all in a meeting. I was a teeny bit overwrought by this stage, what with one thing and another. So I rang the GP's surgery again and blubbed. A nice and very wise GP rang me back and listened for some time. He said some very useful things - not all of which were easy to hear, but the gist of it seemed to be that if it's all going to come to a nasty head, maybe it needs to get worse before it gets better. It is a very complex issue - it's not just anxiety, there are control issues and other things.
Dd is calm tonight and says that when she is in that mood, she thinks a certain way and nothing can shake her out of it or convince her otherwise until she calms down.
For those that don't know - her father (my first husband) was an abusive alcoholic who I divorced when she was 4 and who committed suicide when she was 6 and a half, having treated her in an appalling manner her whole life. That was 6 weeks before I gave birth to her half-brother. Dh's mother died 4 months after that and then my father died a few months after that. The dh's brother and the dog. That last one seems ridiculous but it pretty much finished off 7-year-old dd. And looking back, I did also go a bit bats from stress and lack of sleep. Which didn't help.
All things considered, even if she won't go for counselling, I probably should, as it might make me better at dealing with her.
