Diagnosed autistic

Hi, I'm new here. I have autism level 2 and have just been diagnosed! Bit of a relief, I worried in case I wasn't autistic because it seemed to be me so much. I don't really know where to go from here but it's nice to know who I am a little better at last. Now I'm wondering whether I should tell any of my family or if it would be better to keep it to myself for the time being. I like the idea of telling my loved ones but not everyone understands this sort of thing and I don't want to get judged and ridiculed.
