None of the above stories shock me anymore. Sorry, but true.
My thoughts are:
'You are the only one genuinely fighting for the best for your child. Everyone whose job it is to help, has many other issues on their remit. Your child is just a number to the vast majority of them. Things change when you pay professionals, but only for as long as you can keep paying, if your funds run out, they vanish. Once in a blue moon, you meet someone who really does help. When you do, let them know how much you appreciate it, tell them over and over again and they'll keep helping you (everyone likes the warm fuzzy feeling of lots of compliments, especially when they're heartfelt).
You will loose at least half your friends when you start on the journey of having a special needs child - just at a time when you need them most. You will hit rock bottom in the friends department, and some of your family may be utterly rubbish too. However, as time goes on, you find the support groups, you meet others in the same boat, and just others who understand, and you will make some wonderful new friends. It's taken me a few years, but I now have a super support network. In the meantime, do not be afraid of ringing up support groups and sobbing -they're good people and 'get it'.
You become quite a different person. I've found some parts of the old me have just vanished. I now have the patience of a saint at home, but none what-so-ever with the many twonks I seem to encounter 'out there'. Most of the time I have skin so thick I could give an elephant a run for it's money, yet sometimes sob at a stare from a stranger. Nothing embarrasses me anymore, nothing. My sense of humour has become a little twisted. And, strangely, I like myself more - maybe that has something to do with the fact there is no time for naval gazing these days.
You will hear this over and over in the early days, to the point you will want to deck the person saying it - but it does get a bit easier. Not in the sense of less work, as it's always a lot of work, but in the sense of it becomes less of a trauma and just gradually evolves in to your normal.'
This is what I'd tell someone starting on the path.
