Newley Diagnosed, What Now?

Hi, so my 13yr old daughter has just been screened for autism and we have just had the phone call a couple days ago to say that she has been diagnosed with autism. Even though autism is not divided into three groups any more (mild, moderate, severe) i do believe my daughter would be in the more mild group, but im not a professional. 

we now have to wait for the report to be posted out to us now. but in the mean time, i have no idea what to do, i didnt really understand how i was going to share this with my daughter and what the best way was to do it.

so, what do we do now? what would you advise us to do first and how to go about it? 

Thankyou for reading,
