Blackduckies, just wanted to offer hugs and to say that if you believe something is not right with your DD then you are probably right. Don't give up. Don't take no for an answer. My sister fought for a diagnosis for SIX years for my niece 'who couldn't possibly be' autistic as she didn't tick all the boxes. Finally, at the age of 8, she was diagnosed as having full blown autism.
Goodluck. I hope you find answers x
