I wished I'd posted sooner 
THANK YOU ALL FOR YOUR ADVICE.
I went to the GP a couple of years ago. They wouldn't refer her as she interacted with family, therefore she must be fine 
I asked at school and they said they can't refer her as she doesn't kick off at school. They advised me that GP won't refer as it then comes out of their budget 
I've been back to GP recently and they've now said they'll refer her whenever I'm ready to start the ball rolling.
attila she kicks off big style after school ... some days worse than others. I can tell what kind of day she's had as soon as she comes out of the school door..
mad she now gets just small help, they tell her if any change is happening before it happens, explain it to her. Last year her class had to go the ict suite once a week and just sit anywhere and grab their whiteboard pen. Dd could not do this ... so they allocated her her own seat and pen. Which was great, until someone would sit in her seat, but she couldn't tell them to move. Just little things like that really. But only a very few staff are aware so it's not really ideal. Lunchtime staff are not aware so she's often just sitting alone if her best friend is not there.
I have no idea what SA or ieps are?? .. 
The parent support worker is not a parent! Sorry if it sounded like that. She is a qualified counsellor who liaises with parents to get the best for their child. She fights school if she has to, fights government if she has to. She's there for the good of the child.
SENCO didn't do much tbh. But they say that because she doesn't kick off in school, they are limited as to what they can do.
I definitely have been too easily fobbed off. I NEED to be tougher and fight for dd. I find it hard to be forceful. I think I doubt myself as I've been told for years that I cause her problems and that she only acts up for me! (school tells me this)
When she started school she didn't eat for 2 whole weeks. She was slim anyway but I could count her ribs! She cried constantly. She would only wear a certain pair of socks, certain skirt etc. We had to walk the same way, never change route. The list is endless. Didn't speak to her teacher or other children. At all.
Up until a few months ago we couldn't even go shopping without MAJOR tantrums, tears and flinging arms. Now she will often tolerate a shop.
Everything has been informal so far, I think from your advice now is the time to step it up and make it formal.
