I'm sorry to hear you're having trouble. I'm not sure what to suggest but I wanted to say Hi and bump your post in the hope someone who can advise you might see it!
Perhaps if you post a bit more detail, someone will be able to help. Has your doctor said they suspect your daughter might have an Autism spectrum disorder?
You might be interested to read this article about my friend's daughter, who was diagnosed with an Autism Spectrum disorder at 13! If your daughter does indeed have such a disorder it will be very good if you can get her diagnosed much earlier, as that way she will get the help she needs more quickly. Suzannah (the child in the article, I'll put the url for you below) now gets speech therapy and help with learning social skills, and is doing very well.
