I've just found this forum too, and my 2 cents' worth is that isolation is one of the most stressful parts of raising a child who does not fit into the conventional pigeonholes.
Talking to others is important. Reading is important - and the Davidson site has some excellent resources in this regard. If you are just starting, I'd suggest the six articles by Julia Osborn (just do a search on the site) as an excellent starting point. The more you read, the less isolated you'll feel. But ... it's a big research job.
My only other personal suggestions would be to listen closely to your child, and trust your heart and instincts.
