triggerfish I realise that a lot of this is very scary. My ds was not dx until he was 9 years old and that was because he had a complete and utter breakdown. He too found it very hard at unstructured times (playtimes) and the fear of rejection by his peers was awful.
The teachers always used to write in his reports that he could do better, that he was underachieving. The thing is there is a certain way that AS children have to be taught. They are very bright but they struggle with a social and communication disorder and it is very real.
You need to take this one step at a time now. Go to your GP, ask to be referred to CAMHS for a diagnostic assessment. Tell your GP what has happened, what you believe your ds has. DO NOT WAIT FOR THE SCHOOL TO DO IT. It is not actually their place to do it, it needs a qualified Consultant Psychologist to dx Aspergers.
Do in the meantime apply for an assessment. Tell them your ds is undergoing assessment for Aspergers too.
I have received an awful lot of help from this site ASD Friendly. They have been a godsend to be honest. I too was in your position, waiting for a dx and all the time wondering what I should do. They give honest, friendly and informed advice. You might also, if you read the boards, find that there is alot that is relevant to your ds and it might help you.
I shall log in tomorrow night to see how you are. Take care.
