Daughter aged 7 has just been diagnosed with ASD

Hi, 

My daughter has just been diagnosed with ASD, along with having anxiety and very poor C&L report from school. I was called a few days ago and have had no other support. I am waiting for CAMHS to call me back as she has been with them since Sept 2020. What do I need to do as a parent how does this change things for her and us as a family?
