H.D.
I have a son with Autism as well, it gets better:) I don't live in your specific area but here are some places to try and find support:
Facebook- do a search of Autism and Georgia. I guarantee there will be a group.
MeetUp-Check the MeetUp website to see if there are any support groups in your area for families of Autism.
Generation Rescue (.org)-This is the best place to start with a new diagnosis. You can apply for a grant through them to help pay for medical expenses. Also, you'll be able to find a "Rescue Angel" in your area that you can contact who will help you navigate the biomedical intervention side of Autism. A rescue angel is another parent who has successfully recovered their child and is full of an amazing wealth of knowledge. They can also turn you to other groups in your specific area that you may have not known existed.
You have a long road ahead of you but my child is now 8 and he is in a typical clasroom for 80% of his day with no aid. It's a fight till the end but hang in there and take it one day at a time as I promise, it gets better:)
