Hello to all. Your advice is needed

My name is Ruth currently living in the Oxfordshire area.

I am a mother of a 16 years old girl whom we now suspect has Asperger's Syndrome. The more I research the symptoms, the more I am becoming convinced my daughter needs to see a specialist capable of confirming our suspicion....but where exactly to go? We are a family of low income - so we cannot afford thousands of pounds for a diagnosis. So, my question is, do any of you know where a family with low income can take their 16 years old daughter for a proper diagnosis of Asperger's Syndrome?

I would HIGHLY appreciate any direction on this matter.

Many thanks

Ruth
