What happens next?

My son, who is 6, was only diagnosed on Tuesday. He is bright and school say they never witness any traits (he has officially been diagnosed as ASD). I was just wondering what happens now? Do we have a label and that is that? I got given a booklet saying you can claim some benefits, but I’ve never done any of that kind of thing before. They also told me to book onto a workshop. Can anyone shred any light on the situation for me please. Thanks in advance.
