As an adult who was diagnosed late with Autism I have noticed some parents rejecting an autism diagnosis for thier child. I believe that such a diagnosis does not change anything about the child, the child is the same child - however the diagnosis can act as a signpost to the best ways to understand help and support that child. I would recommend reading books written by people with ASC about thier childhoods - there are many available now, Clair Sainsbury is good as is Donna Williams and John Elder Robinson - to give you some idea of how your son might be feeling. With ASC there are many, many presentations so you will need to use your own judgement as well as gaining support from other parents and people with ASC. You can be your childs best advocate.
Dear A seven
Don't worry you are not going insane at all. You are just experiencing a whole series of totally normal things. It is impossible to say what you are worrying about but it is ok to worry. You need too take a deep breath and take one step at a time. There are going to be wonderful days when every thing is a great success and there are going to be days when absolutely everything goes wrong. The crazy thing is that you never know what each day is going to be ... And in some respects there is very little you can do abouT it. One thing is certain, is that we are all here to help you along the way, so if you have any doubts, fears, or wonderful things to share with us, then please post and we will do what ever we can to help. You are not alone in this. We are all hear to help you.
All the best
