My 4yr old daughter has been diagnosed with Autism

Not my first time posting on here, but last time I had been in a terrible mindset as a parent. My mother and I have put my 4yr old through behavioral testing and the results came back that she is, in fact autistic. I guess I shouldn't be upset about it but I am terrible distraught over this. Perhaps I'm thinking too far into her future, my mind thinks about the terrible ways she could possibly be treated. I myself was diagnosed with ADHD at a young age and I cannot help but feel completely responsible (genetically) for her diagnosis.The staff who observed her said something confusing, that she has Autism but is not on the spectrum. I've looked on the internet and don't entirely understand what that means. They told us that she doesn't understand words or what they mean. She speaks fine but she doesn't understand what "behind, under, over, up, or down" mean. She will just repeat what we say to her. She mostly speaks in music lyrics.To be honest, I don't know where to start. I don't know how to teach her. I know this doesn't change her, she will always be herself. But knowing what I now know, I don't really know how to help her. I don't know where to even begin my research. She will be given educational aid as she grows, but that will be happening in the next six or so months. Until then I don't know how to actually supplement and help her.If there is any advice anyone is willing to lend I will be so appreciative.
