"CAMHS support for my daughter"

My oldest daughter has been attending camhs for just over two years, these appointments used to be every week now if its lucky its once a month. My daughter was referred for a diagnoses of autism but was told she had to many inconsistencies, she has behavioural problems which has resulted in myself having some minor injury's. I was made feel by the camhs worker  that this was my fault due to  my parenting skills and the way I discipline my child. I called camhs after I had a breakdown due to the lack of help and support I receive the person I spoke to on the phone was very concerned but couldn't help as they weren't my child's worker, but promised the worker on the case would be in touch but heard nothing. Two years down the line and am no further forward things have only gotten worse. No help whatsoever from the service put in place
