Hi, Ive just joined this forum, have been loking into ASD since I spoke to my GP about my 8 year old son a few months back.
I am looking for some reassurance really that this is the right thing to do, and views, opinions, on how a diagnosis is perceived in the UK, and whether it will help/hinder my child.

For some background info, I have been struggling with my son for the past 6 years,its got to the point of feeling like groundhog day, the same day played over and over and nothing I do makes any difference, his anxiety is getting worse, he is developing more and more stims -noises mostly, making a circle over his eye when recounting or explaining something. He doesnt seem to 'get' cause and effect, takes everything really personal, has to have everything explained in detail, and is change resistant - even when we take an alternative route to the supermarket he is visably ditressed.
One day he flew into a rage after school over something trivial someone said something was yellow when it was blue, he lost it completely. He hurt his smaller brother quite badly, spat in my face, shouted the most awful things. I just felt I cant cope and everything is out of control.  
The thing is I could see myself in him, so I went to the GP to voice once again, as I have done on several occasions, concerns about his anxiety and behaviour. I have been plagued by anxiety, social disconnection, emotional confusion, to some degree all my life and I didnt want him to become 'me'.  I never thought of ASD as a possibility until the Gp asked questions about aspergers.

The GP has now reffered him to CAMHS for assesment.
My nephew has been diagnosed aspergers and I took the online 'test' and had the result that it was very likely that I am a aspie.
My concern though is that should, as i suspect, my son be 'labelled' he will treated differently, at school and eventually in the workplace.
theres no doubt we need help, I cant begin to think of another day like this let alone the rest of his life, but will we get help, can I get it without official diagnosis? Ive been told there is a long waiting list in my area, over 6 months, I have 4 children and reading up on ASD I suspect that one of my younger boys may also be on the spectrum and Im finding this all really overwhelming.
