my 4 year old has been under assessment since 2012 , via playgroup, his social communication skills became an issue.
Having relatives and a lot of experience myself of ASD I noticed things from being as young as 18months,
There was a crossing of wires in the communication so this letter ended up on our doorstep with no warning 
so reeling from that,
What i'm finding the hardest , most frustrating is the 'I don 't believe it' response i'm getting from people close to me, he's more high end asperger level, articulate,bright, inquisitive does seek social interaction but struggles.
I can't afford to live in denial why should they, as callous as that may sound, plus perhaps wrongly, it gives me the feeling that well if you disbelieve the diagnosis, you must think all his issues are my fault then.
sorry most of that is gibberish, just still a bit overwhelmed, final meeting in a few weeks.
