How do you cope and raise a child with Aspbergers Syndrome or High-Functioning Autism?

I need help! There is a possibility that my 4 year old might have Aspbergers or High-Functioning Autism and I’m freaking out. I want to know as a parent what are the challenges you face, What’s involved in raising a child with this syndrome, What are your personal challenges if you have this syndrome or know someone who does. What resources do you use to cope. What medical treatments do they go through? Can it be averted if caught at a young age/ How? etc. I’ve done some online research but am looking for some first, second or even third had experience/insight.

I feel that asking these questions and knowing what’s ahead of me is the only way I can cope right now.

Thank you for helping me sort this out.
